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.
