Hojbjerg - who's never afraid to shoot - has a particularly ambitious effort from outside the box that spins some distance wide of the target.
56'
Tierney drives down the left well and stands a cross up to the back post for Pepe. He strikes it on the volley well and it cannons up off the ground and smacks off the crossbar!
51'
AUBAMEYANG! Lacazette charges into the box and gets a bit of fortune as the ball is cleared into him. Aubameyang latches onto the ball on the left and fires across goal, but it's deflected just wide!
49'
Sokratis volleys a corner at goal and it hits Armstrong's hand and goes over the bar! However, a VAR check is conducted and no penalty is awarded, presumably because the midfielder's hand was in a natural position.

We're back for the second half!
