Given the extent of scouting in professional football, it's not
surprising.
He could have signed Drogba, that's a fact. But whether he could
have developed into the player he is today is however a big
uncertainty.
Even at Chelsea, it wasn't till Mourinho came that Drogba became
a really good player.
There are similarities between him and Adebayor and given
Wenger's good track record in developing players, that possibility
was definitely there.
But you would also have to consider if he went Arsenal would he
have had the same oppurtunties he had at Chelsea? Especially since
Henry was would still have been playing for the Gunners?
