84'
OFF THE POST! It's the angle of post and crossbar as Paul Tierney waves play on as Milivojevic appeals for a foul... Nketiah sizes this up 25 yards out and his right-foot curler strikes the woodwork with Guaita beaten!

Attempt missed.
Martin Ødegaard left footed shot from the centre of the box is close, but misses to the left.

WIDE!
Nice diagonal from Xhaka finds Saka on the right. He sizes up Mitchell and cuts back inside onto his left foot but his shot is high, wide and not troubling Guaita.
57'

BLOCK! Nice footwork from Odegaard allows him to manufacture a shot from Cedric's pass. The Norwegian finds some space and is able to turn but Guehi makes an important block.
