Mikel Arteta's side made it seven successive wins in the Premier League to restore their eight-point lead at the top of the table
Arsenal answered Manchester City's win against Liverpool earlier on Saturday with a comfortable 4-1 success against Leeds United to restore their eight-point advantage at the top of the Premier League.
Mikel Arteta's side were far from their best, but two goals from Gabriel Jesus — his first since October — were enough to see them to a seventh successive league success.
Ben White was also on target for Arsenal, as was Granit Xhaka, while a deflected Rasmus Kristensen shot 15 minutes from time at least gave the travelling Leeds fans something to cheer.
