Casemiro fed up, ready to leave Manchester United in January

Casemiro arrived at Manchester United amid high expectations. 

Despite a promising start at Old Trafford, the Brazilian's performance has notably declined this season, coinciding with a dip in United's overall form. 

Erik ten Hag's men have suffered 12 losses across competitions and a premature exit from both the Champions League and a sixth-place standing in the Premier League. 

According to 90min, Casemiro who has been sidelined due to injury since October, is considering a move to Saudi Arabia with sufficient interest surfacing from the Middle East.

The report further states that Casemiro now accepts this may be the right time to leave United, with interest from the Saudi Pro League remaining very high.
