Arteta won the FA Cup with them in his first season. Plus 2 community shields, not that they mean much.
My point is that Woolwich hired Emery to get him over the line and he didn't. They've had far more success with managerial punts. But they haven't won the league for over 20 years, so if they did try and hire someone to 'get them over the line', I severely doubt they would.
Liverpool just hired Slot, whose record was less than Ten Hag, and he won the league comfortably.
There's no precedent to hiring someone to take you up a level. We tried it with Mourinho and Conte and would have been far better hiring Sherwood again in all reality, because those two clowns just made a mess of everything
