It's not because he played for Everton. I think Viera is a really good option too. We need to find the next Pep, Zidane etc. We need to find the exception. it's going to take trial and error, we need to find the Pocchetino before he is at Spurs for example. otherwise we stuck fighting for 6th in perpetuity
Re Poch, he’d never finished higher than 8th in the league anywhere before he went to Spurs.
That sort of record wouldn’t preclude Silva from doing the same sort of progression.
