Valencia will have to up their offer for Benfica man Enzo Perez by around £4 million if they want to beat Manchester United to his signature.
According to TalkSPORT, reports in Portugal claim Valencia are the only team to make an official bid for Perez, but Benfica have turned down the approach and are holding out for a bigger offer.
After Singapore businessman Peter Lim took over at the Mestalla earlier this year, it's common knowledge Valencia have money to spend, and Benfica will not sale for anything less than their valuation.
The news may come as a boost to United, who were rumoured to be interested in taking the Argentine international to Old Trafford.
With new Manchester United boss Louis van Gaal currently focused on the Netherlands World Cup campaign, he has yet to confirm or deny any interest in Perez.
Despite no official bid, Perez claimed there is a definite interest from the Premier League side, yet he still decided to sign a new deal at Benfica this year.
The new contract keeps him in Portugal until 2018 and was signed just before Perez left to meet up with Alejandro Sabella's World Cup squad.
Perez' inclusion came as a surprise to some, with Ever Banega expected to make the squad instead.
However, it was Perez who got the nod and he'll be hoping to add to the nine caps he already has.
Benfica will perhaps also be keen for their midfield man to impress this summer, knowing his value will only rise should he perform well in Brazil.
Interest in the 28-year-old has been largely duo to Benfica's incredible achievements last season - the club won three domestic titles, including a first league title in four years, as well as reaching the final of the Europa League for the second consecutive season.
Perez was an almost ever present in Jorge Jesus' side, and was severely missed in the Europa League final defeat against Sevilla for which he was suspended.
Should Valencia get their way, Jesus will have to get used to playing without Perez, a man he bought to Benfica three years ago.
The midfielder arrived from Estudiantes in the summer of 2011, though a knee injury halted his process and he returned to his former club for the second half of the 2011/2012 season.
The following two campaigns have been far more successful for Perez, but his time in Portugal could now be over.
Though no exact figure has been confirmed, it is understood Valencia's bid fell £4million short of Benfica's valuation, and that could prompt Manchester United and van Gaal to act quickly.
