"We were really motivated for today and I have won this stage before a couple of times. The wind was always going to make it difficult today, it was a block head wind and we thought it was going to be cross. Actually it was more a cross head wind so you were never really comfortable. We knew we were going to have to take control and the team were really motivated after yesterday. Obviously we were in control at the beginning of yesterday but then with the puncture of Edvald it really put the team in a difficult situation. It also made it harder for us to take the overall today so we really had to be on top of our game to make sure we finished on the top step of the podium. The lads did it perfectly on the final laps when it was hectic, keeping me in the front and out of danger, so I was ready for the sprint," Cavendish quoted by website of his Team Dimension Data after his victory, referring to race leader Edvald Boasson Hagen from his team who lost the gold jersey after a puncture in the late stages of the race. "Obviously it's nice to be wearing gold now, but I know I am only wearing it on behalf of Edvald. He only lost it because of bad luck and not through any other kind of cause. He should be the guy wearing this gold jersey but we are just super happy to keep it in Team Dimension Data. The team made the step up to World Tour this year and we've already won a GC [general classification]," he added.
