This is not to knock Tony Bloom's model, as where it has worked (Caicedo, MacAllister, Bissouma, etc), it has clearly worked very well. Trossard is another example. I know he left heavily out of favour because of his behaviour and attitude, but on form he was virtually unplayable at times. However, I wish we would take more of a mix and match approach, as the likes of Fulham and Nottingham Forest do. Alex Iwobi has been excellent for them the last few times we have played them, and they also tend to go for young players, such as Harry Wilson and Morgan Gibbs-White, who haven't made it at Premier League clubs, or who are on their way down, rather than end of career players.
I am happy with Verbruggen in goal (and one of the positive things Hurzeler has done is to end goalkeeper rotation, which must have helped his confidence, and bar the odd ricket - Tottenham at home and Fulham away he has played very well), but I would be told the reason we wouldn't sign a keeper like Leno is that he wouldn't have any resale value (or wages, but are Fulham that better off than us?). I disagree - I suspect before long one of the Manchester clubs will make Fulham an offer they can't refuse, then Fulham will probably buy Kelleher. I'm not saying we should have bought Leno, just using him as an example of the type of player they go for. Also, taking Trossard as an example, some of our recent signings seem to be more experimental than previously, whereas Trossard was Captain of Genk when we signed him and, as far as I know, already an established Belgian international. Such players are obviously going to take longer to fit well together in a team.
Kelleher is a brilliant goalie, the complete package. I hope his next club is at CL level, wherever that might be in Europe. Craven Cottage would be just a waste with his prime years ahead of him.
