We discuss what went on and what led to the breakdown in the relationship between Dumoulin and Sunweb. We also ask what this move means for him personally, and for Jumbo-Visma, who are amassing a very strong Grand Tour arsenal.   Next up, we bring you a trio of interesting stories from the Arctic Race of Norway. First up, we hear from Dutch sensation Mathieu van der Poel on his build-up to the World Championships next month, and ask: Can he really win it? We also hear from Steve Cummings, who was back on the front foot after a poor Tour de France and poor couple of seasons, and Warren Barguil, who raged at another rider after losing the race by a single second on the final day.    Finally, with the Vuelta a España starting on Saturday, we look ahead to the final Grand Tour of the season. We're joined by our resident Spaniard Alasdair Fotheringham to get the low-down on what to expect in Spain over the next three weeks.
