Real Madrid dressing room believes Casemiro's departure to Man United is an “Unforgivable sin”!

Real Madrid's dressing room and coaching staff believe club president Florentino Perez made a blunder by selling Casemiro to Manchester United last summer, Catalan outlet El Nacional has reported. It has been claimed that they miss Casemiro’s consistent displays and the leadership he provided off the pitch.
Under Perez, Real Madrid has been uncompromising when it comes to their transfer policy. They have unhesitantly sold players who do not wish to remain at the club and have brought in promising young footballers as replacements.
Similar to Cristiano Ronaldo’s transfer to Juventus, Los Blancos shook the world last summer by shipping Casemiro off to Manchester United in an €80 million deal. Days before the Brazilian’s transfer, the club purchased highly-rated young defensive midfielder Aurelien Tchouameni for a similar fee, who was a like-for-like replacement for Casemiro.
While swapping Casemiro for a younger player was seen as a positive move at the time, the perception has reportedly changed over the course of the season. It is believed that Perez may have overlooked the inevitable adaptation period every newcomer goes through, which can significantly hurt their output.
Tchouameni, 23, has tapered off following a positive start to life at Real Madrid. Once a regular, the France international has recently struggled for minutes under Carlo Ancelotti, with the Italian often picking Eduardo Camavinga ahead of him.
Casemiro, 31, on the other hand, has emerged as one of Manchester United’s best players, winning his place under Erik ten Hag following a difficult start in England. Casemiro also scored the opening goal in Manchester United’s 2-0 EFL Cup final win over Newcastle United on 26 February.
Casemiro has played 35 games for Manchester United this season, scoring five times and providing five assists.
