The World road race champion was knocked off the top spot after Nairo Quintana (Movistar) won the Vuelta a Espana, but a win in the Grand Prix Cycliste de Quebec, and second in the Grand Prix Cycliste de Montreal, helped Sagan keep in touch. He sits second in the rankings on 585 points, with Quintana on 609. With third placed rider Chris Froome (Team Sky) not set to race again this season, it looks like a two-man race for the WorldTour lead.
The WorldTour points are more of an objective for his team, however, with Sagan typically more concerned with winning bike racings and finding his form ahead of his Worlds defence next month in Doha.
"It was great to get back on track in Québec and Montréal last weekend, and I really wasn't expecting to win so that was good to confirm the legs were still there," he said in a statement released by the team.
"I’ve never raced the Eneco Tour before but it's a race that suits my strengths and together with a strong team I think that we can go for some good results."
Sagan will race the European Championships in France on Sunday before taking a private flight to the Eneco Tour.
The Tinkoff team for the race also includes Polish national time trial champion Maciej Bodnar and Michael Valgren but the team's director, Tristan Hoffman, has made it clear that Sagan is the main focus of the squad's ambitions.
"Of course with Peter here, he will be our absolute leader. And we have some strong guys around him including Bodnar who should be up there in the time trial. Then we have Valgren who could be a possibility for the overall fight depending on how the race develops, but our principle focus is Peter.
