Rafael van der Vaart has launched a scathing attack on Erik ten Hag - with the former Tottenham man adamant that the Manchester United chief has given himself a major headache with the "very stupid" decision to integrate Casemiro gradually into his squad.
Ten Hag quickly identified midfield as an area that needed strengthening after arriving at Old Trafford and Casemiro was signed from Real Madrid after the club finally abandoned their efforts to prise Frenkie de Jong away from Barcelona.
Casemiro is one of the most respected defensive midfielders in Europe and is a multi-time Champions League winner from his time at the Bernabeu. However, the Brazilian enforcer has been eased into life in the Premier League, with Ten Hag keeping faith with Scott McTominay for Sunday's crunch Manchester derby.
