Nick Ames was at the Estádio D Afonso Henriques for the Guardian and this is how he saw this wet Wednesday afternoon’s action unfold.

Shkodron Mustafi speaks: “They throw everything up front,” he tells BT Sport, having said he wished he’d scored a little later. “It’s not organised any more and they keep crossing. I think we could have done better but in the end we have to accept it and take the point home with us. I think we could have dealt with it earlier and stopped them making the cross, but we have to accept it and take the point. They are a good side.”

Group F standings: Arsenal still have a bit of work to do to guarantee their passage through to the knockout stages, but even they seem unlikely to mess it up with two games to spare. Vitoria’s interest in this competition will not extend to the new year, but they will be annoyed not to have taken all three points from this game, given the many chances they created.

Peep! Peep! Peeeeeeeeep! It’s all over in Portugal, where Arsenal have surrendered another lead. They dominated possession throughout and created very little but went ahead through Shkodron Mustafi. A late rally by Vitoria in the knockings was enough to earn them a draw, but not the win they needed to keep any hopes of qualifying for the knockout stages alive.

90+3 min: Back to the equaliser. Edwards got the better of Holding down the right flank and crossed to the far post. The ball was headed downwards and Duarte demonstrated perfect technique to get airborne and with an acrobatic swivel his hips fire home with his left peg.

90+2 min: Crikey! Shkodran Mustafi goes perilously close to scoring an own goal after unwittingly deflecting a flick into the penalty area narrowly wide of his own goal after good work down the left from Edwards. Arsenal manage to defend the corner.

The home side equalise and it’s no more than they deserve. An acrobatic finish from Duarte, whose left-footed volley leaves them in with a squeak of snatching the win with four minutes of added time to go.

90 min: Bonatini blazes over the bar to ruin Vitoria’s best move of the night. They carved Arsenal open, with Duarte and Rochinha combining to tee up the substitute with a glorious opportunity to equalise from close range.

89 min: Matteo Guendouzi is felled in midfield and wins a free-kick as the clock ticks down.

86 min: Marcus Edwards has an attempted through ball into the Arsenal penalty area blocked by Holding. Assuming they fail to win, Vitoria will feel they left this one behind them tonight - they’ve had plenty of chances, but were unable to convert any of them into goals. Arsenal, by contrast, have scored with their only effort on target and look like labouring their way to victory.

84 min: Rob Holding puts the ball behind for a corner after intercepting a Rafa Soares cross. The ensuing set=piece is cleared comfortably.

82 min: Arsenal score with their first effort on target, meaning Vitoria goalkeeper Douglas still hasn’t made a save. The Portuguese side make their final substitution, with Leo Bonatini, on loan from Wolves, replacing Lucas Evangelista. They must win tonight, to have any chance of progressing to the knockout stages. I suspect the opportunity has passed them by.

Pepe curls the ball towards the far post, where Mustafi rises highest and sends a fine downward header back across the face of goal and into the bottom left-hand corner.

80 min: Martinelli goes down under a challenge from Evangelista and Arsenal have a free-kick from about 35 yards out, well left of centre.

78 min: Arsenal substitution: Lucas Torreria on for Joe Willock.

76 min: Arsenal are allowed to play the ball around at the back uncontested and unpressed by any Vitoria players. They seem happy to do exactly that. And indeed, for all the penetration they’ve displayed up front they might as well just pass it around at the back.

75 min: Play resumes with a Vitoria free-kick, about 25 yards from goal in line with the left edge of the penalty area. Evangelista stands over the ball, but chips it straight into the arms of Martinez. A poor, poor effort.

72 min: Arsenal continue to dominate and create nothing. They concede a free-kick, however, when Guendouzi hauls Rochinha to the ground. He clatters into Mustafi on his way down and has to receive medical treatment.

68 min: Vitoria substitution: Davidson off, Diogo Rochinha on. Bolton fans may remember the 24-year-old Portuguese, who made four appearances for them on a loan spell from Benfica four years ago.

65 min: A comically bedraggled looking Rob Holding gets booked for a trip on Lucas Evangelista. That looked a bit harsh, as the two players crossed each other’s paths and it’s difficult to know who - if anyone - fouled who. The rain has been relentless tonight and there’s a bit of surface water on the pitch. We’re not into comedy splashing and aqua-planing territory yet, mind.

64 min: Sokratis puts a cross from the left into the stand. Vitoria substitution, halfway inside the Arsenal half. Arsenal substitution: Alexandre Lacazette comes on for Bukayo Saka.

63 min: Mustafi heads over the bar from a Nicolas Pepe corner.

62 min: Vitoria substitution: the number of players on the pitch named Pepe is halved with one hoist of the fourth official’s board - Vitoria’s midfielder is replaced by Dennis-Will Poha, who is on loan at the club from Rennes.

60 min: From the edge of the penalty area, Guendouzi plays a weighted pass to the edge of the six-yard box for Nicolas Pepe to latch on to. the Frenchman is flagged for offside.

59 min: Arsenal continue to dominate possession but are doing little or nothing with it. They’ve been incredibly pedestrian tonight.

58 min: Rafa Soares hacks the ball out for a corner under pressure from Saka. The ensuing dead ball delivery is poor and Evangelista heads clear.

55 min: Kieran Tierney threads a weighted pass between two defenders for Saka to chase down the inside left channel. He’s flagged for offside but that looked very tight indeed.

52 min: Nicolas Pepe loses the ball, allowing Davidson to charge up the left flank. His attempt to square the ball across the face of the Arsenal goal is atrocious and goes wide. Arsenal substitution: Matteo Guendouzi replaces the hamstrung Dani Ceballos, who limps straight back to the dressing-room.

51 min: Joe Willock tries to advance into the Vitoria penalty area, but is dispossessed by Lucas Evangelista. Arsenal are bossing this second half in the early stages, but are seriously lacking in anything resembling cutting edge.

50 min: Ceballos pulls up with what looks like a hamstring injury to his left leg and signals to the bench. He then carries on, but is clutching the back of his leg.

47 min: A rogue pass to Rob Holding results in Vitoria winning the ball and Marcus Edwards galloping into the space left by the Arsenal skipper. With Ceballos racing back to provide cover, the Vitoria midfielder hesitates briefly and what looked a great chance for him to go clean through on goal goes to waste.

47 min: A marauding run up the inside left from Martinelli, who plays the ball inside for Saka and runs on to collect the return pass. It’s overhit.

46 min: It continues to hammer down with rain and the confused mess that is Arsenal gets the ball rolling for the second half. There are no changes in personnel on either side.

Peep! The deadline remains unbroken in Guimares, but it’s the home side who have enjoyed all the best chances. THey’ve brought several smart saves out of Arsenal goalkeeper Emiliano Martinez, while Arsenal have yet to test his opposite number, Douglas.

44 min: Saka and Tierney both go down injured for Arsenal and Pepe is penalised for his foul on the young Scot. Free-kick for Arsenal, just outside the Vitoria box. Nicolas Pepe fires a poor effort high over the bar.

42 min: Arsenal throw-in, deep in Vitoria territory as approach half-time. Holding loses the ball and Edwards surges forward. Rushing back to recover, Holding fouls his fellow Englishman. He’s fortunate to avoid a booking.

41 min: Evangelista becomes the latest Vitoria player to shoot high and wide of the Arsenal goal with a speculative shot from distance.

40 min: A series of free-kicks for fouls on players from both teams has made things a little scrappy. With Davidson lurking in the penalty area, trying to get on the end of a deft little back-heel from Evangelista, Sokratis takes no chances and hacks the ball into Row Z.
