Mansell says Button could kiss career/title goodbye
The 27-year-old Briton is still driving for Honda, which offers him a limited opportunity for success in the current standings, and Mansell feels that he blew his big chance for glory by not doing more while racing in a more competitive car with the then named BAR-Honda in 2004.
The 54-year-old, who won the F1 crown with Williams in 1992, said: "Jenson should have won more races, he has under-performed and that is down to him. He had the opportunity and he didn't take it; there won't be any more."
He added: "Jenson is a great talent. But he was far better years ago than he is now because he was hungry then. He's got a great reputation for partying and that's taken the edge off it. He's a typical example of too much, too soon."
