Bukayo Saka's first Premier League goal helped Arsenal beat Wolverhampton Wanderers 2-0 and move to within three points of their sixth-placed opponents.
The 18-year-old winger broke the deadlock two minutes before half-time, finishing superbly with a volley from Kieran Tierney's cross.
Adama Traore's lobbed finish dropped wide of a post as Wolves pushed for an equaliser.
But substitute Alexandre Lacazette fired past Rui Patricio to seal the Gunners' victory four minutes from time.
Joe Willock, another second-half replacement, almost added a third, but his effort was cleared off the line.
A third straight Premier League win for the Gunners moves them up to seventh place, one place behind Wolves and six points adrift of fourth-placed Manchester United.
