Valencia insist Nicolas Otamendi is not looking to leave the club this summer despite reported interest from Manchester United.
Earlier in May, Los Che confirmed coveted full-back Jose Luis Gaya had committed to a new five-year contract, a move that also raised his release clause to €50m (£36m, $56m) to help end growing interest from Real Madrid and Chelsea.
But the club may face a tougher fight in retaining the services of powerful centre-half Otamendi, who has played an integral role in the club's impressive campaign that could see them reclaim a place in the Champions League next term.
Valencia sporting director Francisco Rufete insists the player had made no indication he wants to leave, also hinting they will enter talks with the defender over a new deal at the end of the season in a bid to stave off interest.
"We are very clear about Otamendi. We want him to play for us for a long time to come. Nico knows that and so far he's not come to me to say he wants to speak about things being different from that," Rufete told AS. "As soon as the season is over, we'll be talking to him about staying for longer."
Adding a centre-half is expected to be a priority for United manager Louis van Gaal ahead of the summer transfer window. Borussia Dortmund captain Mats Hummels remains the most heavily linked with a move to Old Trafford.
United began their recruitment drive in May after confirming a deal to sign Memphis Depay from PSV Einhoven in June.
