Buffon was 23/24 when he joined Juve from Parma.... and had played tons of games!
Abidal unknown? Abidal was with Lyon in the time when they dominated the French League.
I don't think Transfer request is binding on the employer. As for the TC and Mou talk, as per Telegraph, Mou wants to make him his #1, and is lobbying to bring him back against the wishes of the club's gk coach.
I'm only doing so to illustrate that playing behind a high-line defense isn't as easy as just putting the supposed world's #1 in the box. Its a demanding task, and requires a certain disposition and skill to execute it. MAtS has the profile and the experience in such a capacity since his youth years. TC doesn't.
Haha are you really trying to think of players to try and prove your point? The 7 players you listed originally were completely different to the Stegan situation. Also like I said before for every 1 who succeeds 20 fail.. and Barca are NOT in a position to take that risk!
@DonAK Although you must agree with me that there is a potential risk in signing a young player like Stegan while bashing your head on that wall. I just think a GK with actual experience in big competitions was needed.. and what @Moose said confirmed that I believe Courtois could adapt if not already have the ability to pass at the back and have excellent footwork..
