'We are no better off.'
Except for the money we get from Tottenham in your example.
Unless he refuses to sign a contract and walks away for free
None of which is a reason to keep playing Schwarzer past his best.
I have yet to see any empirical evidence that Schwarzer is declining, just personal opinion
And how on god's green earth would someone find and demonstarte "empirical proof" on this subject. Here's what you get from observation, though. Last season, Schwarzer's distribution was far less accurate and far more tentative than the season before. Everything else about his game was just as good. THIS season, Schwarzer still has distribution problems, but his judgement on when to come out and when to stay put has slipped NOTICABLY. Yesterday was the third match I can remember where it looked as if he were pawing at a swarm of bees at times. Yes, only three matches, but that's about 2 more than less season. I call this deteriorating form. If he's our keeper for four more seasons, that's four more seasons of deterioration while Stickdale is increasingly competent for a club we're competing with.
Yes, he made a brilliant save, but it seems to me that Stockwell did that a few times last year while he was our player of the month as well as MotM once or twice.
Old sporting maxim: you're always better getting rid of a player a season too early than a season too late.
Again, all that is happening is people arguing points using opinion. I could argue that Schwarzer is better than ever because I have a gut feeling. Neither of us are correct until there is some hard evidence.
The hard evidence for me is that we have continued to be defensively sound, even with a constantly changing back 4 and Schwarzer has made no howlers (yet).
I like Stockdale, but it seems to me that we are just creating a problem for ourselves by forcing out a great keeper (one of Fulham's best ever) for a young and very promising keeper, but who has played a total of 14 games in the premier league.
Introducing young keepers is difficult, even ones who previously looked good - Ben Foster was the next big thing when he was at loan at Watford in the prem a few years ago. Then he struggled at Man United and had to resurrect his career at the baggies (who are hardly watertight)
