Mikel Arteta hailed Arsenal's emphatic 3-1 win against Chelsea on Saturday as a "turning point" in his troubled side's season. Arteta's side sat just three points above the relegation zone before kick-off at the Emirates Stadium after their worst start to a season since 1974-75.

But the Gunners produced their best performance this term to out-class their London rivals. Alexandre Lacazette's controversial penalty opened the scoring before Granit Xhaka's superb free-kick increased Arsenal's lead before half-time.
