Manchester United have already had a £27 million bid for Valencia defender Nicolas Otamendi rejected, according to Spanish football expert Guillem Balague.
The Sky Sports pundit revealed there is an expectation on the Spanish club's part that the Red Devils will come back in for the Argentina international this summer, but will be required to pay the full £38.2 million buy-out clause written into his contract.
Louis van Gaal is on the lookout for central defensive reinforcements at Old Trafford and has also been linked with a move for Borussia Dortmund captain Mats Hummels.
However, Valencia remain confident that Otamendi is still Manchester United's first-choice option, and believe the club will meet the South American stopper's asking price when the transfer window reopens.
"Valencia think that Manchester United will pay the £38.2 million buy-out clause in the summer for Nicolás Otamendi," explained Balague. "United have already offered £27 million and Valencia think they'll improve on that offer, so the club are preparing for it."
The difference in valuations currently stands at £11.2 million, which is a significant amount of money that could potentially be reinvested in other areas of the Manchester United squad.
It depends how determined Van Gaal is to bring Otamendi to the Theatre of Dreams, but he'll just have to accept that the club must pay top dollar for the majority of players identified for a prospective transfer given how much they spent during the previous summer window.
Hummels is also valued by Dortmund at £37 million so there is little wriggle room between the top two centre-back targets, so don't be surprised if the Red Devils press ahead with plans to sign the 27-year-old Argentinian, particularly after it recently emerged that Chelsea have joined the race for the World Cup winner's signature.
Dani Alves offer
Manchester United have submitted a formal offer to representatives of Dani Alves to see if the Barcelona right-back is interested in moving to Old Trafford this summer.
The Brazil international has only a few months remaining on his current contract at Camp Nou and so will be available on a free transfer in the summer.
Herrera eyed as Xavi successor
Barcelona have identified Manchester United favourite Ander Herrera as the potential successor to Camp Nou legend Xavi Hernandez, and are preparing an attempt to lure the Spaniard to Catalunya.
Barca boss Luis Enrique sees the 25-year-old - who only joined the Red Devils last summer - as the ideal replacement for the veteran midfielder, although they'll have to wait until 2016 when their transfer ban is lifted before making a move.
