Di Resta, who has completed three seasons with Force India, said staying in F1 with the Silverstone squad was unlikely.
"(Force India) are speaking to me every two or three days," said Di Resta.
"They may be interested. They may not. I believe they are in talks with Sergio Perez. It's looking likely that I will not be driving," he was was quoted as saying by Mirror Wednesday.
Force India are yet to announce Nico Hulkenberg's teammate for the 2014 season. Di Resta partnered Adrian Sutil in 2013.
The 27-year-old said Sauber could be a possibility and he was open to a DTM return.
"The only team that really has any possibility is Sauber. There has been nothing other than a chat with my manager. I am also speaking to Mercedes-Benz for DTM," he said of the Championship he won in 2010.
