Inevitably, as soon as Felipe Massa became a force to be reckoned with in Formula One he would be compared to the master behind the wheel and his fellow countryman - Ayrton Senna. Senna, a multiple world champion in F1, is rightly regarded as one of the best drivers of all-time and of any era, while Massa is still looking to make his mark in a sport that is increasingly becoming wide open at the top of the rankings. Is it right for people to compare him to Senna? Is there any way truly to compare one sportsman to one from another era? Are there any other similarities beyond the obvious: they are both Brazilian and both drove in Formula One? Have your say now!
