MARINA BAY, Singapore -- Sergio Perez says it is "just a matter of time" before he signs a new contract with Force India, admitting it is a difficult time to secure a top drive in Formula One.
Perez had been linked with a move to Renault for 2018, but with Toro Rosso driver Carlos Sainz expected to join the French team as part of a wider deal for Toro Rosso to switch from Renault engines to Honda, the Mexican's options now appear to be limited. The top three teams -- Mercedes, Ferrari and Red Bull -- have all announced their driver line-ups for 2018, making a contract extension at Force India Perez's best option.
