A DISAPPOINTED Lewis Hamilton admitted he and McLaren got it wrong by running without the F-duct at Monza today (Saturday) in Italian Grand Prix qualifying.

The McLaren Mercedes Formula 1 star from Herts could only qualify fifth around Monza’s historic circuit, despite being one of the favourites for pole.

Fernando Alonso will start from pole position tomorrow (Sunday) in front of Ferrari’s home fans, with Hamilton’s McLaren colleague Jenson Button – who did use the F-duct – also on the front row of the grid.

Ferrari F1 driver Felipe Massa and Red Bull’s Mark Webber also qualified ahead of Hamilton, who will go from the third row alongside Sebastian Vettel.

A dejected Hamilton, 25, said: “I’m a little bit disappointed.

“It would appear that we took the wrong route by running without the F-duct this weekend.

“I just didn’t have the downforce today, and the car was sliding in the corners.

“I couldn’t push any harder because the car just wouldn’t give me any more.”

The 2010 Italian Grand Prix starts at 1pm on Sunday. The race is being shown live on BBC1.
