Paul di Resta says he hasn't given up on Formula 1 and that he will do "whatever he can to fulfil that ambition".

The Scot was dropped by Force India at the end of last season and this year has returned to the DTM, the series he won in 2010 before graduating to the pinnacle of the sport. However, his return has not gone especially well and to date he has only scored 12 points, his best result a fourth place at the Motorsport Arena Oschersleben earlier this season.

"Iloved F1; Ienjoyed every single thing about it," the 28-year-old said in an interview with the heraldscotland.com. "It's the best racing there is and you are up there with la creme de la creme, so obviously it was disappointing not to get the chance to be involved this season. But you have to put up with setbacks and it's how you react to these things which matter.

"Iam confident people have seen that Ihave the qualities to succeed in F1 but, of course, things keep changing in the sport, whether it's the rules or the driver line-ups and, unfortunately, the situation arose where there wasn't a place for me.

"Iam still young enough to believe Ican gain another opportunity and Iam pushing as hard as Ican to make it happen. It obviously helps if you can bring a lot of money to the table, but Iworked hard to earn my chance in the first place and I'm not going anywhere. Iwant to be back in F1 and Iwill do whatever Ican to fulfil that ambition."

Asked about his plans for next year and if he might get that chance of a comeback, he added: "It's too early to say what my plans are for 2015 and my thoughts are completely devoted to chasing better results in DTM and helping Mercedes in any way Ican.

"But Iam positive Ican gain another drive in Formula 1 and, if anything, Iam even more determined than I was. The decision isn't up to me, but Idelivered good, steady performances and Ihave no doubt I can build on that."
