From that Webber interview, and what I've heard, does seem like there will be a lot of activity at the club this summer in terms of outgoings and incomings...and we have more money to spend on incomings for sure.
I remember when we went down under AN he said about how he kept the squad the same, and when he was sacked he mentioned in an interview how he wished he had made more changes to the squad and freshened it up. Sounds like Webber is intending to freshen it up, and from what I have heard almost certainly Leitner is going, Vrancic/Trybull likely too and we will try to shift Drmic (albeit we will do well to find someone to buy him!!!)
Saw some of your posts about midfielders Bears - I think we're likely to see Sorenson replace Trybull/Leitner as he is more that type of player, than a Tettey. I think Tettey/Sitti will rotate next year, with the idea Sitti will be good enough to take over full time after a season of play.
Also noted your post re: Jamal Lewis and Crystal Palace. I also heard similar, so there must be something in it...
