Manchester United is reportedly interested in signing Richard Rios, a midfielder from Benfica, as they look to strengthen their squad. With the confirmed departure of Casemiro and the potential sale of Manuel Ugarte, the club aims to acquire at least two new midfielders. Rios, valued at £39 million, is seen as a cost-effective option compared to other targets like Anderson Elliot and Sandro Tonali, each costing around £100 million. The 25-year-old Colombian, who previously played for Flamengo and Palmeiras, has made 42 appearances for Benfica this season, contributing five goals and five assists. However, there is a notable valuation discrepancy between the clubs, with Manchester United valuing Rios at £26 million. Rios has also garnered attention for his work ethic, with former Benfica manager Jose Mourinho previously commenting that he 'runs too much,' highlighting areas for tactical improvement.
