The 21-year-old is also being watched by a swarm of European clubs like Brighton, Espanyol, Genk and Red Bull Salzburg.
Kalajdzic currently plays for his country’s club FC Admira Wacker Modling.
The 6ft 5-inch tall striker has scored 6 goals and provided an assist in 9 games this season in the Austrian Bundesliga.
He has made considerable appearances for his nation’s U-21 side and soon expected to get his main team call-up.
The Austrian prospect also scored in Saturday’s 2-1 win against Hartberg.
Palace looking to offload Benteke?
The Eagles are citing the Austrian youngster as a replacement for the £27 million-rated Belgian striker Christian Benteke.
The 28-year-old, who failed to create an impact this season, has still a year left with his contract.
Why should Leeds consider a move for Kalajdzic?
Leeds are already having two in-form strikers namely Patrick Bamford and Kemar Roofe, who have been pivotal in their side’s promotion push this season.
However, Bamford is criticized for his inconsistency, while Roofe has become injury-prone.
The Whites certainly lacked a missing piece in their attacking prowess, even the manager Marcelo Bielsa admitted the fact.
The Argentine manager should acquire the services of Kalajdzic in order to strengthen the Whites’ attack.
But first and foremost, Leeds have to ensure a place in the Premier League next season. Only then, could they persuade the Austrian prospect to Elland Road.
