|1/7||Barcelona are 1/7 with PaddyPower to beat Ajax on Wednesday.
The 20-year-old is set to come face-to-face with the Barcelona star when the Eredivisie champions visit Camp Nou for their opening Champions League Group H clash on Wednesday.
But, rather than be overawed by the occasion, Denswil insists it will be a "huge boost" for his fledgling career to enter into battle with the four-time Ballon d'Or winner.
"He [Messi] is just an opponent and he's not in my team," Denswil told NuSport. "I am not going to let him score, am I? We have to fight for each other and try to stop him. Barcelona will try to win the match - but so will we."
Denswil added that he would enjoy the chance to swap shirts with Messi at the final whistle - but made it clear that he will not ask for the opportunity.
"He's one of the best players in the world so it would be nice if I would get his shirt. But I won't ask for it," he added.
Wednesday's clash kicks off at Camp Nou at 19:45BST.
