It's a debut for Arsenal's Charlie Patino, 18, who is meant to be a bit of a wonderkid. Emile Smith Rowe is replaced.

Arsenal are completely in control now.

I actually feel sorry for Denver Hume now. Nicolas Pepe nutmegs him again - the EXACT same move as last time - before finding Martin Odegaard. His shot is blocked.

That is Eddie Nketiah's first senior hat-trick. He's done it plenty of times for England's youth teams.

A bad first touch denies Eddie Nketiah a chance for a fourth. Nuno Tavares powers in a cross which Nketiah tries to take in his stride. The ball hits his knee though and he can't reach it.

Arsenal replace the booked Folarin Balogun with Granit Xhaka to shore things up.

Arsenal's Folarin Balogun is booked for fouling Denver Hume.
