Maradona’s name was left off the guest list for Friday’s star-studded event in Rosario.
His legendary countryman insists that he holds no grudge and still considers Messi to be a top professional and man.
Maradona, who is currently in Russia for the Confederations Cup, told Sovetskiy Sport: “I congratulate Messi; he knows how much I love him.
“My invitation to the wedding was lost somewhere, but my attitude towards Messi will not change because of this. He is a good athlete and an excellent guy.”
Messi’s international team-mates Angel Di Maria, Sergio Romero and Maxi Rodrgiuez were in attendance.
As were Messi’s Barca team-mates of past and present Neymar, Luis Suarez, Javier Mascherano, Xavi, Samuel Eto’o and Carles Puyol.
