These commotions normally happens when things doesn't go as per the plan. A few months ago, during the Euro Cup there was some infighting among the French players as well. But then, the team management makes sure that everything gets resolved quickly and the news doesn't get leaked in to the media. What happened this time is that some of the unhappy players leaked the information to the press. Even before their match against Croatia, there was disagreement within the Belgian camp regarding selection of some of the players.
Yes, I have also heard about the news, fortunately the French players were able to quickly forget about this problem and focus on the main goal of competing in the world cup 2022 and in the end they progressed smoothly to the round of 16.
World Cup ended for Belgium and those players and we must wait for a few weeks to get confirmation for the rumors. Because initially we only knew it is rumor, we should not believe rumor is true. It can be or can not be true and before having confirmation, we should consider it as piece of information.
Internal conflict or not, finally Belgium did not have a good World Cup and their team will havd big change which started a resignment of their coach. Not sure some star players will resign from their team too.
The world cup this time is really the last for the Belgian golden generation and that also makes it the worst world cup they got. Even though there have been many out there who have favored Belgium to advance to the quarter-finals, but in fact that won't materialize and you have to go home early in the group stage.
You could see that there was a problem between them, when Hazard play on second half and Bruyne gave the captain bracelet to Hazard he tried to communicate but Hazard immediately left him, made worse by Lukaku who missed some good chances it's a shame rare playing at the club has affected his performance so much, so we have to pay enough attention to all possibilities when betting on the World Cup this time but all bets like that will be unexpected.
We can't avoid that moment is where they don't get along anymore. These Belgian players are no longer able to adapt together and I hope that the new coach will find a good solution for the Belgian Red Devils team. Lukaku was indeed very careless and could not take advantage of the opportunities that existed, it seems that when that happened De Bruyne was already getting frustrated with Lukaku's poor performance.
