Intermarche is a Belgium team and have invested heavily on support for their biggest star Girmay, who could be a future star in the classics and other one-day races for years.
Pozzovivos results are nice and fair play to him for pushing on last year, when he didnt a have team. Intermarche gave him a spot and he rode really well for them last season, but it is not like he could demand them to offer him higher wages because of it. He will have to ride on the same premise as last year. They will give him a spot, for this amount of pay and he will ride for the best result in the races he wants.
It is nothing personal, but he is not irreplaceable and they have other priorities. Pozzovivo provides great value and is almost like a luxury to have for them, but it stops being great value if they have to pay him more for his services. The sponsor may see it the same way. Results in the classics and the Tour is the most important thing for them.
