Havent read all the posts as it's likely much the same sort of stuff. But here is my opinion:
Redknapp is a decent manager. He would do very well as England manager. He probably could have taken us further forward, but only to a point. Do I hate Redknapp as some do? Did he fuck up the end of his last season after an excellent first 2/3rds? Yes. No. He got us CL one year and a great runs of games in it, and he played entertaining football. Redknapp though, has gone, so I think it's pointless anyone wishing him back. I liked Redknapp, but I don't wish him back, it would be pointless and we don't need him as we have AVB.
When AVB first arrived I thought it was a risk and could go either way. Talented manager, but he would be under a lot of pressure. He had a slow start because the media were dying for him to fail and the team had to make quite a drastic change in style of play. But, he managed it, and got the most out of the likes of Bale, and the team were playing in a controlled way, and he almost got us CL in his first season in charge, without the striker we so clearly needed. He occationally made mistakes which cost us, which I think show a lack of experience but he is a young manager, so that isn't a fault in my eyes. He got us our record number of points despite this. I think that was pretty fantastic, and I'm right behind him. He will do even better this next season, I am certain of it.
