With Evenepoel a marked man, Dekker thinks the use of Wout van Aert - whether as a sprint option or an attacking threat - could prove decisive.
"I don't think it will be that easy for them," Dekker said. "Evenepoel won in Australia by attacking from far out, but they aren't going to let him ride away again, are they?
"Van Aert admittedly rode a good Vuelta, but it is hard to say for him too. In sprints he gets beaten one time, while the next he competes in a mass sprint."
Evenepoel solo win in Montreal?
He sees an Evenepoel solo effort as the Belgian's best chance for a gold medal in Canada, and thinks that the Red Bull rider could use the climb and subsequent rolling terrain to his advantage.
"But you can sense in almost everything that it is going to fail. I think Remco will be given room to go until the last lap. Then he could arrive alone, which is of course a realistic scenario."
For van den Berg, control is the word. He backs Evenepoel to make a long range move, and if the race comes back together, use van Aert as an option in the finale. He also thinks the Visma rider could sacrifice his chances for Evenepoel if it becomes clear that the circuit is too difficult for him.
Van Aert's role in Belgium tactics
Van den Berg said: "It's quite simple: they need to take control. Evenepoel can make his move five laps from the end, and only in the final lap do they play the Van Aert card."
"All other scenarios become too complicated. Then you try to act smarter than the French and you overplay your hand. Then it becomes a s**tshow.
"Although it is also a scenario where Wout says after six laps that it isn't for him and he sacrifices himself for Evenepoel. The other way around, that won't happen."
