Michu has become one of the leading names in the Premier League since his arrival in 2012, and Wenger, who has frequently been linked with the Spaniard, has compared his versatility in attack to that of Bergkamp.
The Frenchman told the Daily Mail: "I see him like a little bit, position-wise, like a Bergkamp, more than an up-front striker.
"They can play with both strikers because Michu's the kind of striker who is a midfielder as well. He can play both positions, that's why they are 4-4-1-1 or you can call that a 4-4-2 when Wilfried Bony plays."
The 27-year-old has already contributed five goals in 10 appearances for the Swans this season.
