I'm not so sure about that. The team are actually hoping (maybe even expecting?) him to take another big step in the classics and to be able to lead the team.
Quotes from Sporza articles:
Soudal Quick-Step: "We start the spring classics with a squad of free agents (don't really know how to translate "vrijbuiters") but if Magnier continues to develop rapidly we will ride for him as our leader."
Paul Magnier himself: "I don't come to the classics just to discover them. I can do that on training too. Of course my ambition is to be in the wheel of the top riders. If I can follow Van Aert, Van der Poel and Pedersen, that's a good sign. Then it is not up to me to make the race, but to wait for the final sprint."
Yves Lampaert: "We are not doing as well in the classics as we used to, but thanks to a few young guys, we can start the classics again with more courage. I am thinking of Paul Magnier, who has a lot of potential. As a neo pro, he finished 2nd in Plouay. Then you can also compete in Kuurne or Wevelgem. In those smaller classics, we should definitely be competitive."
