The Spanish midfielder spent 11 years with the Yellow Submarine between 2002 and 2013, before joining the New York Cosmos, who he still represents.
However, the 38-year-old is now eyeing a return to Spain.
"I think it's going to be a great season for Villarreal. I'll always follow them. It's my home. In the future the idea is to go back and live nearby," he told AS.
"If I have the chance to re-join the club I'd be very happy."
Senna made 28 appearances for Spain between 2006 and 2010.
