Mikel Arteta admitted Arsenal "dropped our standards" in Wednesday's 2-2 draw against Crystal Palace, which leaves Liverpool on the brink of winning the Premier League.
Jean-Philippe Mateta's 83rd-minute equaliser denied Arsenal victory at Emirates Stadium, meaning Arne Slot's side only need a point against Tottenham Hotspur on Sunday to be crowned English champions for a record-equalling 20th time.
Arsenal took the lead through Jakub Kiwior's third-minute header before Eberechi Eze equalised on 27 minutes with a superb volley from Adam Wharton's corner.
