Dos Santos to quit Tottenham
The former Barcelona winger has struggled to adapt to life in England and has been continuously linked with a move elsewhere. Sevilla were interested in the player, but this month signed Jose Antonio Reyes and so are no longer monitoring the Mexican.
Instead, Villarreal and Atletico Madrid are interested in the player, valued at around 4.5m GBP.
"He's looking to move, to be honest," Redknapp said.
"We had a big bid from Italy last summer but he wants to go back to Spain.
"He's got talent, he just needs to work harder in training and get fitter."
