La Gazzetta dello Sport rumpours that Roglic will lead Jumbo at the tour. Dumoulin will target the giro and the time trial of the olympic games.
Although it´s like in Bernal´s case still a rumour it looks like the Giro fields becomes more interesting than I first expected.
Nibali, Bardet, Fuglsang are already confirmed.
Bernal and Dumoulin are strongly rumoured now. Carapaz and Pogacar are likely in my eyes, too. Perhaps Simon Yates, too.
So a very intersting first grand tour of the year is already guaranteed.
