With the confirmation of Kimi Raikkonen returning to his world championship winning team Ferrari, the main talking point of the paddock now is who will replace his seat for 2014.

But as the growing uncertainty of Grosjean's seat next season is still unclear, we could see two new drivers at the Lotus team next year.

Romain Grosjean has proved himself worthy of an F1 drive over his career so far, with a third place podium finish in both Bahrain and Germany, showing his overall speed and professional ability.

But with races such as Monaco where Grosjean crashed into the back of Daniel Ricciardo, forcing them both to retire; and also Hungary, where Grosjean came into contact with Jenson Button, the question remains: is Romain a reliable enough choice for Lotus to hold onto for another season?

During his GP2 career, Grosjean managed to win the Asia Series championship with four race victories and 61 points overall, once again highlighting he is an incredible driver. However, is a seat in Formula 1 too much for the 27-year-old?

Romain Grosjean says he will "show his value on track" as he attempts to remain at Lotus next season. "I am keeping focused on this season by doing the best job I can for the team and showing my value on track," he told ESPN.

There is no doubt Romain Grosjean will be going into the Singapore Grand Prix full of confidence as he vows to strengthen his performance to assure his drive at Lotus.

"We have some fantastic races ahead and it's going to be a busy couple of months. I'll be pushing to do the very best job I can."

But will his recent run of results continue as we head into the last seven races of the season?

Grosjean's last two race performances have earned him eight points overall with two eighth place finishes in Belgium and Italy and has also finished outside the points four times this season, including two retirements.

So will the departure of Kimi Raikkonen strengthen Romain Grosjean's chances of better race results next season and a position in the 2014 Lotus team or will Lotus have to revamp their drivers for the start of the 2014 season?

What is certain is that Romain will have to show his true capability on the track for the next few races as Formula 1 heads into Asia.
