48'
SAVE! Lokonga picks out Xhaka through the middle and he sweeps it out to Tierney with his first touch. He cuts inside and goes for goal instead of swinging in a cross this time, but his low shot is held by Raya at the near post.

SHOT!
Canos again involved. He decides against shooting from 30 yards but plays a one-two with Onyeka. He gets the return but spoons an effort way over Leno's crossbar. I'm sure he can be forgiven for that one.
