Union Berlin chief Oliver Ruhnert has admitted interest in Inter Milan fullback Robin Gosens.
Union are in the market for a new fullback and Germany international Gosens is on the shortlist.
Ruhnert said: "He's a player who just played in the Champions League final. He's certainly a profile of interest to us.
“But there are also other players we're interested in.
“We'll be playing in the Champions League, but we're not a Champions League club.
“We also have other targets in mind than Gosen. But Gosens would be a very interesting player for us, no doubt of that."
