I think generally speaking we're a little reliant on what happens with Martin, Naismith and Jarvis. With all 3 under contract we can't guarantee someone will take them off our hands.
If they do, that give us a bit more flexibility. If we can't, then like GJP says I would expect us to be looking to sell anyone who's gained some reasonable interest - any of Klose, Pinto, Maddison, Murphy, Oliveira you would suspect.
Worth noting the transfer market isn't an easy job for Webber - it's not like he's come into a championship club with a championship wage bill. He's come into a championship club with a half premier league wage bill - so balancing that alongside new signings is probably why he initially send it'll take 3 or 4 transfer windows to get the squad he wants.
Reality is, were we, for example, to sell Maddison, Murphy and Oliveira and lose our opening 3 fixtures next season then the entire project could easily be destroyed because the fans will simply not put up with it. So they have to balance the books whilst creating a bit of optimism for the new season. Not particularly easy.
