To be honest, I'm so disillusioned by the club's backing of managers that even though the OP has made a good point, it's just inevitable that all those managers would struggle to see 2 years of their contracts. Even if their debut season would be fantastic (like winning the double (a la Ancelotti) or even treble), they would be under enormous pressure to retain that feat. The moment they struggle their noose would be tightened. We're a doomed proposition for any manager looking to kick their career into another gear, so strike out Klopp, Moyes & Low.
