Impossible to win Tour, Giro and La Vuelta in same year - Stephen Roche

Former Tour de France and Giro d'Italia winner Stephen Roche believes it would be "humanly impossible" for Chris Froome to win all three grand tour races in one year.

Froome completed the Tour and La Vuelta double by winning the latter in Madrid on Sunday but Roche, who won both the Tour and Giro in 1987, does not think any rider could win all three in the same 12 months because of the importance placed on the Tour.
