For Costa, the seven-day WorldTour event will be a return to competition after several weeks of altitude training. The Portuguese rider last raced in June's Tour de Suisse, where he finished fifth overall.
Veteran all-rounder Przemyslaw Niemiec will also be in the lineup for his home race, as will speedster Roberto Ferrari.
"The route will be slightly different from the ones in the last few seasons; a hilly [stage] has been added to the third day of racing. I think that in any case, the [stages] that define the general classification will be the sixth and seventh. Rui Costa is the most outstanding rider in our selection, and Modolo is our speedster for the sprints," said sports director Daniele Righi. "It's worth considering that all seven of our riders are returning to racing after some time off, during which they focused on training for the second part of the season."
