For Arsenal, the situation is laced with peril. Lose and their top-four hopes could be over. Unai Emery’s side have hit a downturn, losing three of their last six league games, but the defeats have come away from home. As Emery has been happy to point out, Arsenal have been impressive at the Emirates. Chelsea are not firing on all cylinders, with goals difficult to come by. January transfer activity (or the lack of it at Arsenal) provides the background noise. David Hytner
