Arsenal boss Arsene Wenger was delighted with Alex Iwobi's performance in victory over Everton.

Though Henrikh Mkhitaryan stole the show with a hat-trick of assists on his first appearance at the Emirates since joining from Manchester United Iwobi was equally impressive, providing one of Aaron Ramsey's three goals.

Particularly encouraging for Wenger was the fluidity of the wingers in his 4-2-3-1 formation, with Iwobi and Mkhitaryan switching flanks and doubling up to probe on Everton weaknesses.

"It was accepted from the start that our two wide players could switch, with Mesut [Ozil] as well," Wenger said.

“That's only possible when you have a good technical level, that you do not lose the ball in important positions. If you lose the ball you're in trouble.

“In the first half we didn't, we moved the ball well and it becomes a danger."
