Have you seen the video clip of him after the final at the weekend complaining to Bruno that he hadn't passed to him at the end when they were already 2-0 up?
It sums his winning mentality up.
I know the debate has been touched upon here regarding whether it has been Casemiro or Haaland who has improved their team most this season.
Haaland has scored a hatful of goals but I think the statistics suggest he has not improved City as a team - I believe they have scored a similar number of goals to the same point this season as last, and have conceded more.
Whilst Ten Hag has been a massive influence, Casemiro has been absolutely central to the improvement on the pitch at United. In terms of impact on the team, he beats Haaland hands down in my (admittedly rather biased) view.
