I'm sort of still having difficulty with this, having watched it over and over. I just don't see what's controversial about it. He wipes out Gvardiol. He doesn't touch the ball, and he knows very well he's not getting close to touching it. Yes, Gvardiol's momentum takes him into him. But he just bars his route, and wipes him out.
It's not important. We won 5-1. But apparently there was quite a lot of discussion about it on the media. Just really puzzled. We do get soft penalties, sometimes, and I try to be scrupulously fair on them. No denying it. This isn't one of them.
