Juan Pablo Montoya raced against Felipe Massa in Formula One for four years and it was plenty of time for him to form an assessment of the ability of Lewis Hamilton's rival for this year's world title.
Montoya, a former Williams and McLaren driver now racing in the American Nascar series, was asked recently whether Massa had the talent to be world champion.

Montoya's evasiveness reflected an apparently widespread belief that it would somehow not be quite right if Massa eroded Hamilton's useful but far from commanding seven-point advantage in the three remaining Grands Prix and won this year's drivers' title.
The general perception of the Brazilian throughout F1 is pretty straightforward - he's quick, but a bit wild and unpredictable, and too lacking in consistency and all-round qualities to be considered truly out of the top drawer.
But how fair is that assessment?
