After spending £120M this summer you might expect them to beat a Palace side who've barely trained together all summer.
Pressure's got to be on Arteta after splurging this window. For me the squad's still behind Manchester City, Liverpool, Tottenham and Chelsea in quality. I wouldn't bet against Manchester United finishing above them either, with their new manager.
So raised expectations and a likely finish of sixth in the table (at best), it's not looking good for Arteta. I also wouldn't bet against a managerial change before January.
