The 24-year-old had an excellent year with Stuttgart last season, scoring 17 times in 36 matches across all competitions.
This puts him head and shoulders above any Chelsea player from the previous term.
Quite literally, considering he measures at a mighty 6ft 7in.
He also stood out for Austria at the European Championships, netting in the round of 16 defeat to Italy.
His club manager, Pellegrino Matarazzo, highlighted the strengths he brings to Stuttgart.
“He is dangerous on goal and starts well,” Matazarro told BILD.
“Sasa keeps the balls tight, which is also an important job of a great striker.”
Of course, Kalajdzic is not Chelsea’s first choice when it comes to signing another attacker.
Erling Haaland is on top of the pile, but it feels this particular saga is still stuck in the mud.
