I can´t remember Wenger downright lying. He is often vague or chooses the "no comment" route. Is there a player though where he has publically ruled out as a player we are in for and then signed him though? I can´t think of one.
Anyway, it could be as easy as we hadn´t made contact at the time or something. We are probably not in for him though, which is a pity I think. He could offer a lot of what we are missing.
