Granit Xhaka hit out against Arsenal's mentality during the second half of their 2-2 draw against Watford.
Arsenal lead 2-0 going into the second half before giving up their lead.
"You have to say we are happy to take a point. We were scared in the second half. We knew they would come at us and push us hard but we have to show more character and not be scared. We have spoken about it. We cannot give a performance like this in the second half," said Xhaka following the match.
Unai Emery responded to Xhaka's criticism by saying that Arsenal needed to be stronger mentality.
"I think in football you never need to be scared. You need to take that moment as experience for you and for us. We need to be strong in our mentality," said Emery.
