Casemiro didn't walk into the Carrington dressing room on day one of his Manchester United career and lay his medals down on the table, but he did still command immediate respect.
The 30-year-old has made a blistering start to his career at the club, losing just one of the 11 games he has started since his £70million move from Real Madrid, but as well as shining on the pitch, he has already become a leader off it as well.
Under Erik ten Hag the make-up of the United dressing room has shifted since the end of last season. There was a raft of senior departures on free transfers in the summer and the Dutchman has given power to senior players, with David de Gea, Tom Heaton, Harry Maguire and Bruno Fernandes said to be key in terms of leading the dressing room now.
