Montoya 'not ready' to win title

The Colombian finished third in last year's title race, but has only a single grand prix victory to his name despite taking 10 pole positions in his first two seasons in Formula 1.

The Williams team rates Montoya highly, but Head has voiced a fear that the former CART champion could waste his talent.

"I think Juan has enormous talent," he said. "I think he's got quite a way to go to be at a level where he could win a championship.

"I'm sure we'll be having some friendly and open talks over the winter with him, because Juan has immense talent and I think it would be very sad if it got wasted."

"But, unless he can apply his very good level of intellect appropriately, he won't achieve the results that I think he should do and is capable of."

Williams has set a provisional date of January 31 to launch this year's FW25 in Barcelona. The car is expected to be very different to last year's FW24 as the BMW-powered team strive to make up the wide performance gap to Ferrari.
