Roberto Carlos has expressed his sympathy at Lionel Messi's struggles to replicate the success he has achieved with Barcelona on the international stage with Argentina.
Widely considered the best player in the world, the 31-year-old has won 10 Liga titles and four Champions Leagues among many other team honours, while he has also collected five Ballons d'Or.
He has, as yet, failed to reach similar heights with the Argentina national team, however, suffering defeat in the World Cup final in 2014, while also coming up short in the final of Copa America on three previous occasions.
