Chelsea are joining the interest for Atletico Madrid defender Sime Vrsaljko.
TMW says Chelsea are eyeing a summer swoop for Croatia right-back Vrsaljko.
Inter Milan and Napoli have both cooled their interest in the 26-year-old and that has alerted the Blues to a potential move for him.
Vrsaljko, formerly of Dinamo Zagreb, Genoa and Sassuolo, is under contract with Atletico until June 2022 but is possibly leaving Spain after just two seasons.
Manchester United boss Jose Mourinho is also watching Vrsaljko at the World Cup this month.
