Former world champion Sagan and Van Aert hit their heads on last year’s Tour after Sagan used his head and shoulder to push rival Jumbo-Visma into the sprint.
After the finish, Sagan was relegated to last place in the field after initially finishing second on the stage, while Van Aert was also fined for “inappropriate behavior” after lifting his middle finger to Sagan.
In an interview with a Belgian newspaper The newspaper, Bora-Hansgrohe runner Sagan said: “I don’t think I should apologize to anyone.
“Things like this happen in group sprints. Everyone knows how hectic things can get.
“After what he told me in this sprint, I think he should apologize. I thought this five months ago and I still do it today. Well, I’m not going to waste my sleep over it.
The incident occurred during stage 11 of the Tour last year during a group finish in Poitiers.
Sagan was relegated after the sprint finish in Poitiers after using his head and shoulder to push Van Aert 50 meters from the line.
The Slovak, who had finished second in the stage, was pushed back to last place in the peloton, was fined and received a penalty of 13 points in the sprint classification by the commissiares.
But officials also handed rider Jumbo-Visma Van Aert a penalty, after gesturing towards Sagan as the riders crossed the finish line.
After the scene, images emerged of Van Aert raising his middle finger at Sagan as he expressed his frustration with the incident. You can see the photo on Twitter via Flamme Rouge here.
