Ziegler’s contract with Sampdoria is set to expire at the end of the season.
“Ziegler is a perfect match for Stephan Lichtsteiner and they play together in the Swiss national team,” said Biancocelesti President Lotito.
“This is an advantage for both the players and the team. However, current Ziegler is a Sampdoria player.
“It is our general policy not to make moves against the desire of the club. If Sampdoria want to sell, then we are ready, otherwise he can stay there.”
