Arsenal survived a late scare to end their winless run in the Premier League as Mikel Arteta's much-maligned side claimed a thoroughly deserved 3-1 victory over Chelsea.

The Gunners headed into the Boxing Day clash at Emirates Stadium having lost five of their last seven Premier League matches, yet were worthy winners against Frank Lampard's hapless team to mark the one-year anniversary of Arteta's first game in charge in style.

Alexandre Lacazette's penalty put Arsenal ahead in a league game for the first time since a win over Manchester United on November 1, and a stunning Granit Xhaka free-kick doubled their tally.

Bukayo Saka then embarrassed Edouard Mendy early in the second half though, after Tammy Abraham's VAR-awarded goal, Arsenal ultimately had to rely on Bernd Leno's save from Jorginho's penalty to prevent a nervy finish.

That meant Chelsea were condemned to a third defeat in four league games.
