Casemiro shared a dressing room with Cristiano Ronaldo for five trophy-laden years at Real Madrid, though they would spend just a few months together at Manchester United.
They won the lot together at the Santiago Bernabeu, including four Champions League medals. As such, the Brazilian powerhouse would have been able to get on board with the five-time Ballon d'Or winner and his intense demands when he touched down in the Premier League for a fresh challenge.
By that stage, though, Ronaldo had one foot out the door, and his second coming had turned sour. Yet one player who shared so many great moments with him in the Spanish capital is ready to relay the message.
United did right in allowing Ronaldo to leave, as it was abundantly clear his working relationship with Erik ten Hag had reached breaking point.
