The Argentine star will have no shortage of candidates to accompany him in his nuptials, and here at Goal we give our readers the chance to select their favourite!
While nothing has been confirmed at this stage, reports suggest that Lionel Messi is ready to get married to his childhood sweetheart Antonella Roccuzzo.
The couple, who have two children together, are apparently set to tie the knot in their native Rosario next year, with a big party planned to mark the occasion.
But here is the big question: who will Messi choose from his sparkling football career to accompany him down the aisle?
It could be either of the other two members of the MSN, Neymar and Luis Suarez, with whom the Argentine has struck up a strong rapport during their time together at Barcelona.
Or perhaps Sergio Aguero, a close friend of Messi's throughout their time in the Argentina set-up, could be honoured with the best man role.
La Pulga could also choose from two illustrious ex-coaches, Pep Guardiola and Diego Maradona, who in their own way have acted as mentors through his career.
And there is more of a wildcard choice out there too - imagine if none other than Real Madrid's Cristiano Ronaldo received the nod!
