Brazil legend Kaka welcomes Lionel Messi to the elite 'Triple Crown' club in a post on social media.

Argentina's captain became the ninth player in history to achieve the status of 'joining the club,' which requires a player to have won the Champions League, World Cup, and Ballon d'Or.

Kaka, who joined the 'Triple Crown' club in 2007, was quick to praise the PSG superstar following his victory in Qatar earlier this month.

The former Brazilian player shared a graphic on social media with a list of all players who have achieved the feat, including himself and Messi.

Messi just needed a World Cup title to gain entry to the elite club, following his four Champions League titles and seven Ballon d'Or awards earlier in his career.

Ronaldinho, Rivaldo, Zinedine Zidane, Paolo Rossi, Gerd Muller, Franz Beckenbauer, and Bobby Charlton round out the squad.

Messi is yet to feature for PSG since his success in Qatar this month but did show his support for the team via social media during their win over Strasbourg.

The Argentine was still celebrating his country's World Cup victory over France, which ended a 36-year wait. His performance throughout the tournament contributed to a goal in each round of the knockout stages through the tournament.
