Tester Bottas must win races for Williams future

Williams' new test driver must start winning races if he is to progress further in Formula One.

That is the admission of the Grove based team's technical director Sam Michael, referring to Williams' 2010 test and reserve driver Valtteri Bottas.

The 20-year-old Finn is also contesting this year's F3 Euroseries, and he drove in the same series last year as well as British F3, but has won no races so far.

Earlier this month, however, Bottas did win the F3 Masters event at Zandvoort, as he also did in 2009.

"Of course, it was a brilliant performance," Michael is quoted by the Finnish newspaper Turun Sanomat.

"Valtteri is the first person to have won the event twice and the Masters has always meant a lot to Williams.

"But he knows what he needs to do. We all expect him to win the Euroseries and hopefully he will do it soon," added Sam Michael.

"Valterri is a clever guy and he knows that he has to start winning races in F3, and only then will we look together at the next stage."
