Jenson Button says he is relaxed about his contract situation at McLaren having yet to put pen to paper on a deal for 2014.

The 2009 F1 champion is out of contract at the end of the year, with his team having yet to take up the option it has for next season.

The team has previously stated it planned to keep the same drivers for the new campaign while Button has also suggested that he fully intends to stay with the team for another season.

Ahead of this weekend's Singapore Grand Prix, the Briton again insisted he isn't going anywhere and was working on the basis of being in a McLaren again in 2014.

"It's not an issue for either party," he told Sky Sports News of the ongoing talks. "I'm just concentrating on racing and we'll be racing together in 2014."

Button's name had been mentioned alongside other drives in recent months, including Ferrari before confirmation that Kimi Raikkonen would join Fernando Alonso for 2014.

Button has first hand experience of being part of an all-champion line-up from his time alongside Lewis Hamilton, and he said it would be interesting to see how Ferraris partnership developed.

"I've been with Lewis before, we're both World Champions, and that was a pretty interesting atmosphere in the team," he said. "I don't think it was a bad thing - I think it was a good thing for both of us - and we'll see if it's a good thing for those two.

"Alonso's probably used to a different style of team-mate over the last few years with Felipe. A guy who's quick, but pretty much has to do what Fernando says I guess when it comes to team orders. Kimi will not be like that.

"So in one way I think he [Raikkonen]'s going to push him hard, but also he won't get it all his own way."
