I honestly feel his only goal, switching E3 and PR, is to aim as quickly as possible for the full set of 5 monuments. He has LBL, Ronde, Lombardia. So he needs San Remo and Roubaix. He realized that he shouldn't wait until he's 30 to try and win Roubaix. He's in the best shape of his life so he should try as hard as possible, right now. Same for San Remo but he probably realized that one could take 5 more years and all stars aligned. If he would have won San Remo, I'm sure there would be less pressure for riding, let alone winning Roubaix. Now the pressure will be higher. It's his first try and so many things can go wrong, but he can do a Hinault and move on to the next goal. Curious to see how it will play out, but compared to San Remo and especially RVV, his chances vs. MvdP are lowest in Roubaix.
