Arsene Wenger’s biggest mistake in the transfer market?

Arsenal manager Arsene Wenger’s biggest mistake since he joined the English side was just revealed today by Cristiano Ronaldo’s agent who shed some light regarding the star player’s move to Manchester United.

According to Jorge Mendes, Arsenal were the first to eye Ronaldo (like they usually are with talented young players), but lost the player in favor of Manchester United because they were too slow to react (again, like they usually are).

“I remember what happened to Ronaldo at Arsenal,” Mendes said.
