Valencia have opened talks with Ajax over the transfer of Gregory van der Wiel at the end of the season, according to his agent.
Reports in Spanish newspaper Superdeporte claim Valencia have offered a five-year deal to the defender and are now waiting on Ajax's response.
The Netherlands international, who is contracted in Amsterdam until 2013, is valued at €10million but it is thought the Spanish club are looking to capture him for between €6-7m.
Van der Wiel's agent, Hakim Slimani, says the stopper is unlikely to leave Ajax in January.
But he expects the two clubs to reach an agreement over a summer move, telling De Telegraaf: "Valencia is the ideal club and Gregory was already looking for a move to Spain.
"It's now up to the clubs but I expect both sides to reach a deal."
He added: "The chance of him leaving Ajax in the winter break is small but you never know. Usually it's about a transfer at the end of the season."
Slimani says Van der Wiel is looking to emulate fellow Dutchmen Rafael van der Vaart and Nigel de Jong by working his way up before joining a high-profile team.
"Based on advice he wants to go to Valencia," he added. "Gregory is looking to take a gradual path.
"Rafael van der Vaart and Nigel de Jong are perfect examples. Both stopped at Hamburg and that served them well.
"At Valencia he knows he would play, which is important with a view to the Dutch national team."
Van der Wiel, a youth product at Ajax, is also thought to have attracted interest from Chelsea, Bayern Munich and Inter Milan.
