The 22-year-old has spent the campaign at the La Liga side after Chelsea decided his development would be best served elsewhere.
After moving to Stamford Bridge in 2011 from Barcelona he struggled to make an impact and a serious knee injury scuppered his chances of breaking into the first-team.
After recovering from the injury, Romeu has established himself as a key part of Valencia's midfield.
He has made seven league starts for the club, including six since December.
And, speaking to Spanish newspaper Super Deporte, Romeu confirmed he would be open to staying at Valencia.
"My position is like I have always said - I want to be comfortable here," Romeu said.
"I want to give everything to Valencia, have a great year and finish the season well.
"When we finish we will sit down and talk about whatever. I've always said that if I was comfortable and happy, I will continue to fight for a year or whatever."
Romeu would find it extremely difficult to break into the Chelsea team, especially considering Jose Mourinho just spent £21m on Nemanja Matic - a player that occupies a very similar position to the Spaniard.
The Blues also have Ramires, Frank Lampard, Michael Essien Marco van Ginkel and John Obi Mikel in the position.
