Casemiro will sign a four-year contract with an additional year’s option for an initial sum of £60 million plus £10 million in add-ons.
United, which is now last in the Premier League, will host Liverpool on Monday at Old Trafford. They have released a statement to the effect.
After fulling his transfer, Casemiro will become one of Manchester United’s highest-paid players. He follows defender Lisandro Martinez, fullback Tyrell Malacia from Feyenoord, and midfielder Christian Eriksen as the club’s fourth acquisition.
In 2014–15, Casemiro spent a season on loan at Porto in Portugal before returning to Spain the following year as Real Madrid exercised his buy-back clause.
He has 222 appearances and 24 goals for the Spanish powerhouses.
