Felipe Massa warned his seat is not secure by Ferrari

Ferrari president Luca di Montezemolo has warned Felipe Massa that his recent results have not been good enough to secure his future.

Massa has had a poor run of results since Monaco

Massa started the season strongly but in recent races he has struggled to deliver consistently, scoring just 16 points in the last five races. Having had a poor run in 2012 which led to his contract only being a one-year deal this season, Montezemolo said he has warned Massa that his future is in doubt.

"Felipe is a quick driver and a great guy," Montezemolo said in an interview with Corriere della Sera. "But in the past days, we were very clear with him: both he and us need results and points. Then, at some point, we will look one another in the eye and decide what to do."

Montezemolo was also cryptic when it came to the topic of Sebastian Vettel potentially joining the team in the future.

"Sooner or later, every driver sends messages to Ferrari, a dream to be made reality for every champion. Even Ayrton Senna did it. However, even if I have lots of problems, finding drivers for the future is not one of them. Fernando Alonso is a true great, as I've said before. He has proved it and will prove it again, very soon."
