Karun Chandhok admitted that his return to F1 action hadn't gone to plan after he finished 20th in the German Grand Prix.

Chandhok was given the surprise chance to compete at the Nurburgring at the expense of Team Lotus regular Jarno Trulli, marking a return to action for the first time since he was axed by Hispania Racing after last season's British Grand Prix.

The Indian driver started from 20th on the grid and was the final finisher in the same position, some four laps down on winner Lewis Hamilton.

Although pleased to get to the finish, Chandhok admitted that he had paid the price for a lack of time in the car ahead of the weekend.

"That's a full race distance completed and an awful lot of learning under my belt," he said. "Honestly, that probably wasn't the race I wanted - I had a couple of high speed spins and I think I need more time to get used to the tyres. When they start to go off there's very little give compared to last year's rubber, but that's all part of the learning process and I'm glad I got the car home and did the best job I could."

Team-mate Heikki Kovalainen by contrast enjoyed a solid run to 16th place as he once again led the challenge of the three 'new' teams.

"I think that was a pretty good race," he said. "For me everything was working well in the car but honestly it was a bit lonely out there! We're not quite with the guys ahead, and we're well clear of the teams behind, so I wanted to make sure I could push as hard as possible over the full race distance, not make any mistakes and get the car home in one piece.

"We are progressing in the right direction, and it will take time to be able to really fight with the guys in front, but we'll get there."
