According to Grégory Beaud (Blick), Yannick Weber (Pittsburgh Penguins) and Mirco Müller (looking for a new team after his season with Leksands IF) are both looking at the Swiss market.
They are, of course, not the only defensemen interested in a roster spot on a National League team. As Beaud reports, HC Ambrì-Piotta, EHC Biel, and the SC Rapperswil-Jona Lakers have received several CVs of foreign-born defenders.
Apparently, Emil Djuse and Viktor Lööv are two of the players offered to Swiss clubs. Whereas Djuse played for Spartak Moskova this season (six goals, 22 assists in 45 games), Lööv suited up for Jokerit Helsinki (three goals, 16 assists in 55 games).
