He’ll have a scan tomorrow. At the moment, it’s not looking good.”Granit Xhaka was his replacement, a man whose future could be affected by any injury to Partey, and – as we mentioned – he scored the Gunners’ only goal of the game.Mikel Arteta appears to have decided to tie Xhaka down to a longer deal, though.

He is a key member of our squad.”According to several media, the Swiss star will get a contract until June 2025 with an increased salary.On the other end, the above mentioned Abraham seized the opportunity to show himself in front of possibly his new team, as the British media report Arteta is eager to sing him in the next few days to improve his unimpressive attacking firepower.
