Perez was with the team back in 2013, but moved to Force India after just a single season, where he has remained ever since.
The Mexican has not denied that there has been talks between himself and McLaren, and did not deny his interest in the situation either.
“If I had guarantees that I could be competitive, and there was a great project behind everything, then why not?” Perez said.
“But I would have to know the details of their plans better, to understand the situation of the team.”
Considering Perez was the man to bring about the legal action to keep the Force India team in the sport, the Mexican is expected to stay with the team.
He has also been talking up the team’s expectations, and their potential ahead of the Italian Grand Prix.
“There is no doubt that the best of this team is coming,” Perez stated.
“The goal is to be a competitive team in the coming seasons and I think it is possible to even be among the top three.”
Despite all the talk, he has said that he was not letting it affect his performances for the rest of the current campaign.
“I’ve got a contract and I keep performing and I keep delivering at my best,” the Mexican added.
“I try to score as many points as possible for the team, to try to get us further up on the grid. It doesn’t change from that perspective.
“I think we have a competitive car, we proved that in Belgium. We are coming to a similar track in terms of what you run around here.
“We should be quite competitive, and the aim is still the same – to try to be the best of the rest and I think we have a good chance of doing that again.”
