Talking about the hectic sprint finish, Sagan said:
“Today I remembered we are racing again in Belgium because today was like a spring Classic. It was crazy, all day in the front, the trains trying to overtake one against another.”
“It was a crazy day. It started to rain also, and was very dangerous - in the final there was a crash. I’m very happy because team Bora-Hansgrohe and my teammates worked very well and we took another victory, which is amazing for us.”
Sagan was cautious about his chances of winning again on Thursday and so taking his 100th career win. He was also cautious about his GC chances despite having picked up some bonus seconds.
We’ll see. First we have to survive until tomorrow," he said.
"For sure this is very good (taking bonus seconds) but for sure there will come one day where there’ll be a lot of groups and a lot of gaps. It’s about seconds and in the end, day-by-day."
