Australian cyclist Richie Porte claims that he was punched by a fan during a Tour de France stage earlier this week.
Porte is one of race leader Chris Froome's main lieutenants.
Speaking to the Telegraph's cycling podcast, the Team Sky rider said the incident occurred on Tuesday's stage 10.
I was [punched] in the last 3km. I got a full-on punch. It was the same atmosphere on Alpe d’Huez two years ago. They are so anti whatever we are.
Do I deserve to be booed? Does Chris Froome deserve all this? I don’t think so. Maybe in 10 years’ time they’re going to see that these victories are legitimate. It’s a disgrace how some of these people carry on.
Following the Alpe d'Huez stage on the 2013 Tour, Sky team boss Dave Brailsford said that Froome and his teammates were subjected to abuse which included being slapped and hit with a high-pressure water pistol.
The antagonism towards Sky stems from their recent dominance and questions regarding how they have achieved it.
