THE world’s two most celebrated footballers could put their rivalry to one side and don the same strip in a one-off exhibition game. 
Barcelona’s Lionel Messi and Real Madrid’s Cristiano Ronaldo are tipped to appear in a North v South European super-clash.
The La Liga duo would appear for the southern Europe side alongside stars from the French and Italian leagues.
While the northern Europe side would be comprised of the best players from the English, German and Russian leagues.
