Barcelona have reached an agreement with Valencia over a deal that will see Juan Mata move to Nou Camp this summer, according to media reports. The 22-year-old has been impressive over the past few seasons with Valencia but Barcelona's interest in his services wasn't quite obvious. From the same team, Spanish champions Barcelona have been eyeing David Silva and already landed David Villa. It was reported that Barca will pay €20million to sign highly-rated winger Mata. The deal is expected to go through in the space of one month.
