Reports have claimed that Chelsea are willing to let Romeu head out on loan and he has been linked with a move to Celta Vigo.
However, Valencia have emerged as the leading candidates to sign the 21-year-old, according to reports in Spain, and a deal could be concluded next week.
Valencia midfielder Canales, who is a former team-mate of Romeu at youth level for Spain, believes a move to the Mestalla would be good for the ex-Barcelona youngster.
"I have spoken with Oriol and I say sincerely that he is very taken by the option of Valencia," Canales told Superdeporte.
"This squad is perfect for a player to progress."
Romeu joined Chelsea two years ago from Barcelona, but he has been restricted to just 33 appearances during his time at Stamford Bridge.
He was linked with a loan move to Bolton Wanderers 12 months ago and he missed the second half of last season after undergoing a knee operation in December.
