Der Landbote reports that the 25-year old left-back has agreed to a one-and-a-half-year deal with the Canadian outfit with the option of a further year.
However, TFC head coach Ryan Nelsen indicated that he knew nothing of the speculation.
"Geez, that would be a good [signing]. What's he like?" Nelsen said.
"I think he's a pretty decent player actually. So that would be good if a player like that comes in. But we'll see.
"I don't know, I'll have to read those reports from Switzerland and get back to you."
