The PSG star remains hurt by the way Laporta pushed him out of the club last summer.
But the Barca president said at the club's assembly: "It has made me sad since it happened. It is a subject that all the initiatives that there are to make a recognition to all that Messi has given I sign up, I lead them or I go behind whoever leads them. He has given us everything.
"You have made a very correct analysis. For me Leo will always be at Barça. Circumstances made us do what we did but that can't spoil the recognition we have to give him and sooner or later, I hope sooner, we can pay tribute to this player who has given us so many years of glory and without him the last 20 years of Barça would not be understood.
"He has been the cornerstone of these teams. It makes me sad and until we do not solve it, I hope you advise me, it makes me sad and we will have to solve it. In any case, eternal recognition for everything he has done".
