Bukayo Saka and Martin Odegaard scored in the opening half of the game as Arsenal beat Wolverhampton Wanderers 2-1 in the English Premier League on Saturday.
The victory helped Mikel Arteta's Arsenal go four points clear of holders Manchester City at the top of the table, although the latter have a match in hand.
In freezing temperatures, Arsenal made a lightning-fast start and the points always looked secure from the moment captain Odegaard doubled their advantage in the 13th minute.
Saka had given the home side the lead in the sixth minute after some intricate link-up play sent him clear. Wolves re-grouped and gradually began to make a few inroads although Arsenal were untroubled until Matheus Cunha shot powerfully past home keeper David Raya after 86 minutes to set up an unexpectedly nervy climax.
Arsenal have 33 points from 14 games with champions Manchester City, who host Tottenham Hotspur on Sunday, on 29 and Liverpool and Aston Villa, also in action on Sunday, on 28.
