Manchester United are determined to do all they can to prise Juan Mata away from Chelsea. The Daily Star says Chelsea have flatly rejected the idea of selling Mata to a Premier League rival. But sources in Spain insist United have already spoken to Mata's agent and could tempt Chelsea's resolve with a £27m offer.

But any move for Mata looks doomed unless a deal could be agreed to send Wayne Rooney in the opposite direction.

And that is something boss David Moyes has so far refused to contemplate, despite Rooney having struggled with injuries this season.

But Mata wants out of Chelsea as he fears for his World Cup place because of his lack of playing time.

His representatives have also been in contact with Real Madrid, Atletico Madrid and Barcelona. It is thought Chelsea would prefer to sell to Atletico - but the ultimate decision rests with Mata.
