#3. Ronaldinho
One of the most popular names in the game, Brazilian playmaker, Ronaldinho, is another big-name superstar that Arsene Wenger narrowly failed to sign during his Arsenal tenure. The manager was very close to signing the midfielder in 2001 but he could only watch as the player completed a transfer to Paris Saint Germain instead.
The manner in which the move collapsed left Arsene Wenger fuming. The Frenchman had already discussed the deal with the player's brother and everything was going smooth,
However, after failing to secure a work permit from the British Immigration department, the playmaker moved to the Ligue 1 instead. Ronaldinho represented the Parisians for 2 years before moving to Barcelona where he won 2 Ballon d'Or awards and established himself as a club legend.
