Lionel Messi:
Certainly one of the biggest names in this list. Wenger tried to sign three players from Barcelona’s academy in 2003 but the Frenchman could not lure the Argentine prodegy away from the Nou Camp.
“I think in the end he was not so keen to move. It was not completely down to a flat in the end, it was down to the fact that Messi was comfortable at Barcelona.” – Wenger said in 2014.
