SAN JOSE, Calif. -- Barcelona vice-president Jordi Mestre says manager Ernesto Valverde will have the final say on Yerry Mina's future, amid reports of interest from Manchester United and Everton.

Sources have confirmed to ESPN FC that Barca have received approaches for Mina from several clubs, including Premier League sides, following the Colombian defender's impressive World Cup.

Barca currently have six centre-backs in their squad and only three -- Gerard Pique, Samuel Umtiti and new signing Clement Lenglet -- appear guaranteed to be at the club when the season begins.

Therefore, two of Mina, Thomas Vermaelen and Malon Santos are expected to depart Camp Nou this summer.

"It's top secret," Mestre told ESPN FC when asked if United were one of the sides pursuing Mina. "We have to be very careful because Yerry Mina arrived last season and he's very young, but we will see. We will see. The final opinion [on if he stays or goes] is with the coach [Valverde]."
