For the money Dumoulin would demand I doubt there would be many teams that could take him. Trek have signed Nibali, and Porte has another year on his contract. Don't know if Astana could afford him. Movistar will probably sign Mas. Michelton could probably sign him but they would have let the Yates bros go to do it probably. Not sure what their contract situation is. Think they both got extended.
Well considering how Sunweb was unable to give him proper mountain support for years I wouldn't be surprised if he would leave them. The handling of his knee injury obviously worsens the situation too. There are two main questions to ponder on:
1) How expensive breaking the contract is? What price has Doumolin have to pay should he leave now? He still has 2 or 3 years left of his contract.
2) Which teams needs him and could afford him (also considering the price mentioned in 1)?
As for 1 I have no idea but as far as I know Dumoulin's salary isn't that high (around 2 million €?) so the fee for breaking his contract is probably not that high either.
As for 2 I think Astana, Bahrain, INEOS, BORA, UAE, DD, Lotto, CCC and Katusha would consider signing him. From these teams I think Astana, Bahrain, INEOS, UAE and maybe Katusha could afford him. Astana has proper GC riders in Lopez and Fuglsang so I don't think they would offer a serious bid. So like it or not as I see it it's between Bahrain, INEOS and UAE.
As for INEOS they could definitely afford him but they don't really need him. However as Dumoulin is arguably the biggest threat to INEOS in the GCs they might sign him just to strengthen their position immensely. On the other hand Tom wouldn't go to INEOS in my opinion as he values success higher than money and with INEOS it's highly probable that he wouldn't be able to ride for the GC in the TDF for the next 1-2 years despite that it should be his main target from now on.
So I think Bahrain is the most likely option besides staying at Sunweb for one more year.
Lefevre doesn't want to overpay. Doesn't mean he doesn't have the money. He's always bitching about it, doesn't mean it's true. If Deceuninck wants to cross the border, it might be a good investment. Evenepoel could learn from him, and if they really want to keep Remco and nurish him into a GT rider, they need to prep the team anyway.
Well... considering that Roglic (team car) pissing incident and weird tactics that team doesn't really ooze with professionalism
(provided that lack of professionalism is the reason Tom's leaving Sunweb)
But that team would look very impressive on the paper though.
article based on AD but this one mentions that in De Telegraaf other teams interested in Dumoulin are : Team Ineos, CCC, UAE-Emirates, Total Direct Energie but in De telegraaf Dumoulin denies he's changing teams...
