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 "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.
