In the Belgian media he is pretty much idolized, perhaps even more so than Hazard. But i don't think anyone will disagree with the fact that he at the very least is very outspoken, he even admitted it himself iirc. Besides that you can see it clearly in his reactions on and off the field. If he doesn't like something you're gonna notice it. He grew up only a few miles from where i live, and i know someone who knew him when he was kid. Apparently even then he wasn't the most popular kid on the block. He was always knocking on peopl's doors asking if they wanted to play football with him, but rarely anyone ever wanted.
