Barcelona president Josep Maria Bartomeu says he'll be in charge of Leo Messi's contract talks.

Bartomeu spoke to TV3 before Saturday's win against Las Palmas to reassure fans about Messi's contract renewal.

“There are no nerves at all. I want to reassure everyone. I will handle the talks in person to ensure Messi stays here," Bartomeu explained.

And he added: "Everything will be done with discretion. He's the best player in the world, we want him to stay here and we're working on that. We're talking with his people, we want him to stay here and he wants to stay.
