One can only speculate exactly which races he refers to, but the truth is that over his time as a road racer he's already gathered immense success including four monument wins, a World title, a stage and yellow jersey at the Tour de France and much more. However that does not mean the
Alpecin-Deceuninck rider didn't make mistakes in the past and his over-aggressive attitude may have cost him triumphs. However after deciding not to do it anymore, that is now the case once again as he is able to see that long-range attacks arre becoming more and more common in the peloton and he is no longer an outlier.
"But nowadays everyone participates from ninety kilometers before the finish. I am not alone anymore," he says; with great recent examples being those of Tadej Pogacar at Strade Bianche, and his own attacks at the E3 Saxo Classic and Gent-Wevelgem which saw several riders working together with him. "I know that winning the biggest races is much more important than doing something stupid in a race."
