The Dutchman, who was a key domestique in Froome’s 2016 Tour triumph, suffered a knee injury at the Ruta del Sol in mid-February, putting him out of action for a number of months until he returned at the Route du Sud last week.
However despite this lengthy spell on the sidelines, Poels remains upbeat about making Sky’s nine-man squad.
“I’m confident that I’m in the team,” Poels told De Telegraf. “The progress has been clearly visible in recent weeks.
“As one of Froome’s domsetiques, I do not have to be good on the first day. Instead I have to be fresh in the third week in the Alps.”

Poels completed the four-day Route du Sud race in the Pyrenees, where he worked in support of Kenny Elissonde who finished third overall.
“I’ll stay in the Pyrenees for a few days now to explore some of the climbs,” he continued “Those are signs that the team trust in me.
“It has also been mentioned that I will will also start in Vuelta a España. Because I’ve been out for three months, that might be a good idea as I’ll still be fresh.”
