I disagree, and I also remember when the media taunted Wenger for signing a man named Thierry Henry, because he failed at his previous clubs. Funny how Henry turned out to be our greatest-ever player. I don't expect Theo to be the same obviously, but he's still young and has time to learn if he gets first-team football.
Yeah well, he's got an awful lot to learn if you expect him to be good enough to at least clean Henry's boots.
