Sime Vrsaljko will soon confirm that he will make the move to Atletico Madrid from Sassuolo.
The Croatian international has been linked with a potential summer shift to Spain and according to Guillem Balague, the move is highly likely to take place.
Balague explained to Sky Sports that Atletico would love to sign Cesar Azpilicueta from Chelsea but will instead land 24-year-old Vrsaljko from the Modena club he joined from Genoa in 2014.
"If Chelsea were willing to sell, the front runners would be Atletico Madrid although they have recently cooled on the idea, turning their attentions instead to Croatian full-back Sime Vrsaljko, who will soon confirm that he is moving to the Spanish club," he wrote.
Former Dinamo Zagreb star Vrsaljko has impressed for Croatia in two appearances at Euro2016, playing the full 90 minutes as his national team upset reigning champions Spain 2-1 on Tuesday.
