I’m not sure the Haaland transfer is down to a greedy agent in the way you describe it, if his agent was just about money he probably would have sent him to Man Utd where he would have earned a hell of a lot more. The guy has made a sensible step up to one of the smaller ‘big’ clubs who are known for developing talent (Leadowski, Aubemayang etc) and he is already doing well being slowly eased into an attacking young team (Sancho has assisted him a couple of times already) whereas at Man Utd he’d have been thrown in as a starter and expected to be a saviour at a struggling giant. He’s made the right choice there for his career.
In terms of loans, I would say that first of all we do sometimes get players in permanently who have been here on loan. Roofe, Rob Hall, George Thorne are all examples of that, and all probably wouldn’t have joined without coming here on loan first. Secondly, I think it can actually work in your favour - if we do go up, it’s all well and good saying ‘oh no, we have to rebuild the squad’ but imagine the quality of loan players we will be able to bring in at Championship level - the top teams want their best youngsters to be tested there not in L1, and we will already have a lot of cache due to the way we play and the cup runs we’ve had etc, plus the way we’ve developed their players already - so there’s a good chance the likes of Liverpool, Chelsea, Man City and West Ham would lend us some of their top youngsters, players who with all due respect will perform better in the Championship than the likes of Browne or Kelly seem likely to do at the moment, given their past record there.
