Manchester United have identified Real Madrid midfielder Casemiro as a potential alternative to Frenkie de Jong, according to Marca.
The Red Devils have pursued a move for de Jong throughout the summer but have been unable to strike a deal with Barcelona for the Netherlands international.
Therefore, United have turned their attention to Madrid midfielder Casemiro in order to solve their long-term engine room issues.
Erik ten Hag's side have come under plenty of criticism for a lack of midfield resolve in their opening two Premier League defeats to Brentford and Brighton.
