Ruben Neves criticised Arsenal players for the way they celebrated after Mikel Arteta's side defeated Wolves 1-0 on Thursday night.

Top-four rivals Tottenham Hotspur and Manchester United had both slipped up on Wednesday and Tuesday respectively, leaving the Gunners with a golden chance to close the gap on fourth-placed West Ham United, who defeated Watford 1-0 on Tuesday evening.
