Goalkeeper Thibaut Courtois has suggested that he "pointed the finger" at Belgium coach Marc Wilmots after their 3-1 defeat to Wales on Friday night.
Belgium had been tipped to reach the final at Euro 2016 but they let slip a one-goal lead to bow out at the quarter-final stage, like they did at the World Cup two years ago.
Earlier in the tournament, it was reported that Courtois and Wilmots had a disagreement after the defeat to Italy, and Courtois has said that he voiced his opinion in the changing room after the disappointment in Lille.
The 24-year-old told reporters: "This was an opportunity we may not get again. I gave him my opinion in the dressing room. He has to make his own decision.
"I pointed the finger where it had to be put after the game. We have to remain intelligent. We're young and we're going to still spend a lot of time together but it's a disappointment because we had a golden chance to go to the final.
"It's the biggest disappointment of my career and I've played in the final of the Champions League. We started the game well, we created two or three chances and we got the goal. But afterwards we fell back into our half, we left too much space and we couldn't hit back."
Courtois had kept three successive clean sheets before conceding three times on Friday evening.
