Oleksandr Zinchenko returns to the Arsenal starting XI for their Premier League clash against Chelsea at Stamford Bridge.
The Ukrainian has been absent from the Gunners side since the 3-1 win over Tottenham Hotspur at the start of October after suffering a set back with a calf injury. He did however, return to the bench for Thursday night's 1-0 win over FC Zurich that secured top spot in the Europa League group A.
In that game Takehiro Tomiyasu, who has been the starting left back for the past four league matches, came off with a muscular problem that has ruled him out for today meaning Zinchenko is back in. As a result Kieran Tierney is once again on the bench for the Gunners in a Premier League match.
