Arsenal midfielder Granit Xhaka has challenged his teammate Alexandre Lacazette to score away from home.

The French striker, who arrived from Lyon, has scored four league goals for the Gunners, but all of his goals have come at Emirates Stadium.

"He's an important player for us," Xhaka told the club website.

"We know his qualities and you can see that he's ice-cold in front of goal.

"Now he needs to do the same away – then I'll be really pleased."
