Etienne Capoue is pushing hard to leave Watford.
The French midfielder is a top target for Valencia, where he would be reunited with former Hornets coach Javi Gracia.
Gracia has personally requested Capoue's signing and the midfielder is demanding a transfer from Watford.
Watford are prepared to sell Capoue, but want to complete their incoming business first before selling him to Valencia.
After their relegation from the Premier League, Watford have made it clear they wish to clear Capoue's wages off their books.
