The Mexican, who is currently with the national team ahead of its World Cup qualifier against El Salvador, has made just 30 appearances for Spurs since joining from Barcelona in 2008.
The 23-year-old has a year left on his contract and had looked set to end his White Hart Lane misery by moving to Villarreal before the deal collapsed following the Spanish outfit's relegation from La Liga.
Dos Santos previously spent time on loan at Ipswich, Galatasaray and Racing Santander but is unsure as to whether or not he will be allowed to leave this summer.
“I don't know about my future," he told the Daily Mirror. "I want to concentrate on the national team, but after that I will speak to the chairman to see what is going to happen to me. You never know in football. You have to try to do your best to get chances. Maybe I will go, maybe I will stay."
The winger also admitted his joy at being back with the Mexican national team, where he has been a consistent force over the last couple of years.
"It's great to come to the national team and play games," he said. "I'm grateful for the coach to give me the chance. It's a pleasure. I don't have any other offers at the moment. I will speak to my manager and we will see in a few weeks what will happen with my future."
