Xhaka had some talent, decent passing stats, he actually in the end formed a decent partnership with Partey. But he was a massive liability, he was so completely one footed that he’d often give the ball away getting the ball set onto his left foot. He was often guilty of playing blind passes and square passes to no one. And he absolutely could be a red card magnet.
Whether he was a net benefit or detriment to Arsenal is debatable. What isn’t debatable is that we have not missed him one jot
