Werner enjoyed his most productive season last term, scoring 34 times for RB Leipzig.
"He likes to drift to the left and then come in with his right," Marsch told Bleacher Report's Football Ranks podcast.
"He can drag the ball [out wide] and cross it or come across the goal as well.
"He's also good at finishing crosses from the right side when he's attacking in the box, but he's also good in the middle and he's good on the right, too.
"I think if you're playing with two strikers, which is what we did often at Leipzig, we gave them freedom to move to the left.
"We built that in tactically so he could find ways to be on the move but dangerous, but he could play as a second striker, he could play on the right, he can play in a front three, he can play any of those positions.
"Again, he will work against the ball, he will defend, he'll work for the team, and the other thing that's so special about Timo is that for a guy who sprints so much in a game, he's always healthy.
"That's unusual, those sprinters that are so aggressive, they pick up a lot of soft-tissue muscle injuries. Timo has been incredibly fit and hopefully he can stay that way."
