Veron feels former Argentina teammate Javier Zanetti, as Inter's vice-chairman, can convince Messi about the move.
He told Stats Perform News: "I do not think he will move to Italy.
"If he were to do so, it would be if Javier Zanetti convinces him of the project and how important he would be.
"In the end, it's Messi's decision. But if Inter are to have any chance, they must speak to his heart. He knows Zanetti, so there's the entrance."
