Had nothing to do all game really, but did play one nice long pass and it's rare you see a Premier League goalkeeper dressed like Barney the Dinosaur.
Again, another rock solid defensive play, had a shot on target in the first half, and won the penalty by drifting into that position near the corner of their box that he's popped up in so often this season.
Niclas Fullwho?
Wholas Fullkrug?

Unlucky not to score with a right-footed effort that cracked off the post and then hit the keeper. More of than not those rebounds go in

A goal against his former club, very nicely taken on the half-volley. I enjoyed him giving them the eyes after he scored though – they'd been giving him some guff when he was taking corners

Really not sure how he missed that early chance, the ball was bouncing but a player of his quality should tuck that away. Led the team, with Saka, on 4 shots

Made a chance for Timber early on, but hurt in a clash of knees. He tried to carry on when it looked pretty obvious he couldn't, and was eventually replaced by Martin Zubimendi. 3 home PL appearances this season, 3 times he's had to come off hurt before half-time. He can't catch a break, especially frustrating after such a good display midweek.

Pretty lively down the left, one great pass set Rice free and it almost resulted in a chance for Gyokeres

Marked his 200th Premier League appearance with a well-taken penalty. Also got a deliberate slap in the face which gave him a bloody nose, and I though the West Ham player was lucky to get away with that

No questioning the work rate, almost got on the end of a great Rice cross, but otherwise things didn't quite fall for him.

Came on for Odegaard, brought composure to midfield, defended really well, and played the pass for Timber which led to the penalty

Came on, no fuss

A couple of lively moments in a second half where Arsenal never needed to get out of second gear
Not on long enough to rate

Not on long enough to rate
10/10 - Going top of the table, even temporarily. Shows the start to this season has been as bad as presented in some quarters.
