Croatia coach Ante Cacic has left Liverpool defender Dejan Lovren out of his provisional 27-man squad for the European Championship after they fell out in March during a friendly against Hungary.
Lovren was an unused substitute in the 1-1 draw and later made angry remarks about Cacic, who axed him after the centre-back stopped warming up when he realised he would take no part in the game.
"These are the best players we have at our disposal," Cacic told a news conference on Monday.
"Playing in the national team requires good form and total commitment at club and international level. We want to keep a sound atmosphere in the dressing-room.
"I haven't closed the door on Lovren for good, he can return one day if he realises that he has to be a team player," he added.
"When it dawns on him that he can't look down on his team-mates, the staff and the coach, he will perhaps find a way to get back in."
Lovren has stood out for Liverpool recently, scoring a stoppage-time winner in the epic 4-3 second-leg win over Borussia Dortmund which sent the Premier League side into the Europa League semi-finals.
He was also outstanding in the 3-1 aggregate semi-final defeat of Spanish side Villarreal which propelled Liverpool into the final against holders Sevilla in Basel.
Cacic's squad includes six players from Croatian champions Dinamo Zagreb, with 21-year old goalkeeper Dominik Livakovic called up on stand-by.
Croatia are in Group D at 24-nation Euro 2016 along with holders Spain, the Czech Republic and Turkey.
