Not really. Lefevere is always short on money, because he wants to be competitive in all aspects of cycling. Its kind of easy if you only have to pay one superstar and the rest of the team is composed of helpers. But Quickstep has to pay at least one sprinter, a few riders for the cobbles, Alaphilippe wont be cheap either, ...Evenepoel should bring in extra sponsorship for the Belgium Team if he lives up to his undoubted potential though.
So the problem is not sponsorship but how to distribute the money. They could build a decent GT-squad with the money they have. But they wont ever do that cause it would take away from their 50+ wins every season. If they were to pay 5-6 decent support climbers then they would lose quality on the cobbles, in the leadout and/or support for Alaphilippe in the hilly classics.
