Didnt say he was on Sennas level (he isnt),but the best since Senna.
Senna was hard as nails on the track,Scummacher is also hard as nails.Difference imo - Scumacher is a cheat and doesnt have a sporting bone in his body.He has driven bent cars most of his career,he has caused many accidents which could have maimed or killed people.He has deliberately driven other drivers off the track time & time again. The only person I remember Senna doing that to was Prost,and everyone seems to forget that prost did the same thing to him at the same track the previous year.Scumacher doesnt care how he get the result as long as the results state that he crossed the line first. Senna actually had a very strong set of ethics,although admittedly they didnt always seem to be the same as everyone elses,or even make sense sometimes.
I find it interesting that Hamilton constantly mentions Senna and Gilles Villenueve as his heros / influences,but has never mentioned Scumacher in those terms.
