Best available managers currently out of work we should be looking at:
Mauricio Pochettino - Probably not realistic, but we should absolutely contact him first. Best out of work manager in Europe.
Rafa Benitez - A very controversial suggestion, considering his recent spell with Everton, but he's been successful just about everywhere he's been. Newcastle and Liverpool fans both absolutely adore him and his number 1 strength is organizing defensively.
Marcelo Bielsa - Turned a mid-table Championship Leeds side into champions, then finished mid-table in the Prem before the magic wore off. Regardless of the Villa v Leeds rivalry recently, we should definitely consider him.
Marco Rose - Didn't work out for him at Dortmund and I was surprised he wasn't given a bit more time than 1 season, but he was brilliant at Borussia Monchengladbach before that and has all the makings of being the next great German manager.
Potter has been brilliant at Brighton and should also be someone we talk to, but I'm just highlighting that there are others out there who would instantly improve us and would be capable of pushing us into European contention.
