According to Bild, the Premier League side have offered €15 million for the Austrian international.
Stuttgart, however, are holding out for more, with reports suggesting 'Die Schwaben' want around €25 million for Kalajdzic.
Kalajdzic has one year left on his contract with Stuttgart and has been linked with a move away from the club for the past few months.
