West Ham United sold Sebastien Haller to Ajax in January and they are still looking to sign a quality replacement.
According to Daily Mail, the Hammers are keeping tabs on the Stuttgart striker Sasa Kalajdzic.
The 23-year-old has 13 goals and four assists to his name this season and he has been likened to Peter Crouch and Mario Gomez because of his tall frame and playing style.
The Hammers could certainly use a target man like him and the 23-year-old would prove to be a solid long term investment for the Premier League club.
