Paul Di Resta still does not know who will be his team-mate at Force India

Paul Di Resta admits he is surprised that he still does not know who will partner him at Force India this season following Nico Hulkenberg's departure to Sauber.

After a disappointing end to the 2012 season, the Scottish driver says he cannot wait to get back in the car, having scored just two points in the final six races. "For whatever reason nothing went the right way at the end of last season," said Di Resta. "Essentially you always remember the end of a year more than the beginning, and with my crash as well. "There were some good drives, some good pace, but it just never worked out. "I've been through times like that where you just need to dig deep, and eventually you get out of it. Hopefully this year will be the year. "Obviously, when something bad happens you just want to get back in the car the next week and go again, but there has been this lull. "All I can say is I'm looking forward to getting in the car on the first of February, and then testing again a few days later."
