Barcelona remain in contact with Manchester United midfielder Juan Mata.

Off contract at the end of the month, United have confirmed a new deal has been tabled to the Spain international.

Barca, however, are also in contact and exploring the prospect of bringing the former Valencia back to the LaLiga.

A source told ESPN: "The signature of Mata is not a priority, but we must keep an eye on the opportunities of this type in the transfer market.

"He is a free player, with a lot of quality and is very versatile."
