Just because Lukaku and Courtois are highly rated as teenagers doesn't mean that they are going to start games in 6 years for one of the top clubs in Europe, if that's what we believe we'll be. Luiz has already made enough mistakes to gain some critics and create some doubt while Mata has so far started a grand total of 0 games for Chelsea thus we don't have the slightest idea what his Chelsea future holds. It is as simple as comparing other top clubs in the biggest leagues in Europe to their squads in 2005-2006, need I mention how many different Barcelonas and Manchester Uniteds we've seen in those years? As Beast pointed out we don't even know our line-up for this season and frankly I've not had confidence in my knowledge of the ability of all our players since last summer. Until I figure the answer to that question, and that's going to take more than a couple of games since I'm not that eager to cast out and conceder any player who joined us before 09/10 (bar Cech and Ivanovic) washed-up, finished, done etc despite the highly annoying current fad I can't seriously talk about the future of players who are mostly of unknown quality.
