According to Kicker, Stuttgart have upped their asking price to at least €30 million for 24-year-old striker Sasa Kalajdzic with as many as 13 clubs interested in signing the Austrian.
From the Premier League, Manchester United, Chelsea, West Ham, Newcastle, Brighton and Southampton are interested in signing the 2,00m tall striker, who has scored six goals in 15 Bundesliga games this season after missing much of the season through injury.
In addition, Borussia Dortmund are in the market for a replacement to Erling Haaland whilst Bayern Munich have held initial talks with the entourage of Kalajdzic. However, a move to Bayern hinges on the future of Robert Lewandowski.
Elsewhere, PSG are reportedly showing an interest alongside Milan, Napoli, Atlético Madrid and Benfica.
Kalajdzic has just one-year remaining on his current deal and whilst a contract extension hasn’t been ruled out, the likelihood that he leaves in the summer is increasing.
Stuttgart had originally wanted around €20m-€25m for Kalajdzic but with several clubs showing an interest, it could start a bidding war.
