Wolff: I can compete

Following her latest practice run, Susie Wolff believes she has got what it takes to compete against the best.

Wolff replaced Valtteri Bottas in Friday's opening practice session for the Spanish Grand Prix.

The 32-year-old covered 22 laps with a best time of 1:29.708, which put her P14 on the timesheets.

It was her first practice session of the year and her time came in at just 0.8s shy of team-mate Felipe Massa's.

"If I did not think I was capable of racing at this level I would be the first to take myself out of the game," Wolff said.

"I 100 percent believe a woman can compete at this level."

As for Williams' decision to sign Adrian Sutil as their official test driver rather than give her the job, she insisted: "I am in no way bitter about what has happened recently.

"Yes I was disappointed but this is a tough environment. The best drivers are fighting to get in here.

"We all bring something different to the table and we are all fighting for the same opportunities and there are so few opportunities.

"I was well aware it was going to be a tough fight and it is."
