Barcelona superstar Lionel Messi must leave the club if he is to actually prove how great he is. At least, that is the opinion of controversial super-agent Mino Raiola.
Messi has been a Barça player since the age of 13 and has never seriously flirted with the idea of leaving Camp Nou, even when situations such as his current contract saga have emerged - with less than 12 months remaining on his deal. Despite the club announcing an 'agreement' earlier in the summer, the Argentine has continued to put off actually signing.

The five-time Ballon d'Or winner has a huge haul of countless team trophies and personal accolades, as well as having broken individual records galore over the years, but Raiola believes Messi needs a new challenge to really cement his legacy on the world game.
