M-Sport Stobart Ford World Rally Team man Mads Ostberg has revealed that he might not be able to take in any more WRC events this year following this weekend's Rallye Deutschland.

Ostberg has been pretty impressive thus far this season in his Fiesta RS WRC car, and after sensationally taking second in Sweden, has been in the points on four other occasions, taking three fifths - in Mexico, Sardinia and Argentina - and a sixth last time out in Finland.

"It's possible that Germany may be my last event of the season so I want to aim for a top result this week," said the 23-year-old.

"It's going to be difficult as it's my first time driving on asphalt in a World Rally Car since Corsica and Spain in 2008. I competed in last year's Rallye Deutschland and Rally Catalunya in a Ford Fiesta S2000 so I had some experience during those events but it's very different behind the wheel of a World Rally Car.

"I've got a test planned pre-event and I'm hoping that I can find a good feeling in preparation for the rally.

"I think it's going to be a tough event but I hope to be where I was on the last day in Finland, I just need to be pushing from the start and it'd be great to challenge the 'top five' more on this rally."

Britain's Matthew Wilson meanwhile will be in the other M-Sport Stobart Ford car nominated to score manufacturers' points and after finishing sixth in Germany last year, he has said he will be aiming for a similar result.

"Germany will be the first time this year that tyre choice has come into the equation so I think this could be one of the biggest challenges. Of course it is also the first all-tarmac round of the season so it's a big step into the unknown for the Fiesta RS WRC although we will be fortunate to fit in some testing on Monday afternoon," added the Englishman.

"I enjoyed the small sections of asphalt we've had already this year like in Rally Argentina but that is nothing compared to three full days of rallying on the surface.

"Last year was a good result for us and I'd be happy if I finished in a similar position but this is a tough rally and small mistakes can have brutal consequences so it's important to know when to push."
