I understand Everton fans' frustration over the delay but really there is next to no chance of relegation the way the likes of Swansea, West Brom and West Ham are playing - that's not taking into account Palace (5 points) and Huddersfield who are beginning to find life very tough.
There's a lot of dross around the bottom of the league. I include ourselves in that dross, but I think we have enough to keep us out of trouble as long as whoever the manager is, actually organises and manages the team. I just don't see Palace and Swansea having the necessary strength to keep up, so it's them plus another - I wouldn't be surprised by West Brom or West Ham or Stoke if any of those don't pull their finger out asap.
To be honest, I think everyone from Watford down is eminently overtake-able by the current team managed by Unsworth if he gets the players organised and working hard in games. Is Unsworth the man to do the job though? I don't really feel the magic to be honest - though if he gets a run going you never know.
I would like Silva, as I think he would set us up and get personnel in that could implement a good attacking style of play whilst not compromising the defence. He might be on permanent look out for the next big thing, but if he came off, that next big thing could well be us. If we want to get to the level of interesting the Simeones of this world, I think Silva is the man and that's really the reason why I would go for him - if he ain't the best, he is a stepping stone towards the best compared to most of the other names on the list.
