Big two Bundesliga clubs compete for Kalajdzic

Two Bundesliga giants are fighting for the signing of Sasa Kalajdzic. The striker has had an exceptional season for Stuttgart, which has put on Bayern Munich and Borussia Dortmund's agenda.
Bayern's interest is due to the possible departure of Robert Lewandowski to Barcelona. That means they must bolster their attack. However, he is not Bayern's top priority so that could see him go to Dortmund.
According to 'Bild', Borussia Dortmund are the ones in the lead. In their attempt to get Sadio Mane, Bayern have allowed Dortmund to work on attracting the Austrian player. In addition, Marco Rose's side could enjoy more game time there than at the German side.
Sasa Kalajdzic's numbers last season shows his quality in front of goal. He has scored six goals for his team in 15 matches he has played. It was a difficult season for Stuttgart who stayed up on the final day of the season.
