Leeds United are looking to bolster their defence this summer as they prepare for life back in the English Premier League, and they have brought in Germany international centre-back Robin Koch from Bundesliga outfit Freiburg.

The Elland Road outfit have now been linked with an interest in Dinamo Zagreb centre-back Josko Gvardiol.

The 18-year-old can also play at left-back and is also on the radar of Bundesliga and Champions League giants Bayern Munich due to his huge potential.

Leeds are already in talks with Zagreb and they could end up parting with £18 million for the services of the 6ft 2ins defender.

Whites fans have done their own scouting on Gvardiol thanks to YouTube, and they reckon he would be a fine addition to head coach Marcelo Bielsa’s squad.

Here is how some of them have reacted to the news on Twitter:

Didn’t know who Josko Gvardiol was 3 hours ago and now I’m 100% sure he’s the best young centre back on earth
