Speculation has intensified in recent weeks over where the Santos star will be plying his trade next season, with Barcelona currently attempting to negotiate a deal despite the player's insistence he will remain in Brazil until 2014.
However, should such a move materialise, Messi feels the starlet would add a different dimension to Barca's attacking threat.
"I do not know if he will end up at the club or not. However, it is true that he is a player who would bring a very different dimension to the team," he told Qatar Alkass. "Of course he would be a wonderful addition."
The Argentina international then looked ahead to next year's World Cup in Brazil and insists he wants to taste glory at the tournament irrespective of what it could mean for his reputation in the history of the game.
"All I care about is winning the World Cup," he said. "I won't be thinking about whether it will mean I am the best player ever or not."
The 25-year-old also praised former coaches Frank Rijkaard and Bayern Munich-bound Pep Guardiola, a man who Messi believes will be a huge hit and Bayern and wherever he chooses to go in future.
"He [Rijkaard] was the one who believed in me when I was 17," the Argentina skipper added. "It was one of the most important times of my life working under him, and Pep told me I was the best player he has ever coached.
"He will succeed at Bayern. He will succeed anywhere he goes because his understanding and reading of the game is like nobody else's."
