Arsenal boss Mikel Arteta is happy with Thomas Partey's public show of commitment.

The Ghana midfielder, after victory over Luton midweek, declared his "head is with Arsenal", despite speculation of a move away this summer.

Asked about the comments, Arteta replied: "He better have his head here because that is what we expect!

"And we need him. He is a top player and you can see the impact he can have on games."

The Gunners go to Brighton on Saturday.
