Manchester United legend Roy Keane has slammed Fred and Scott McTominay for their drab display against Brentford at Old Trafford. The Red Devils lost 1-2 to the Seagulls, and Keane has put some of the blame on the shoulders of the United midfield duo.Speaking to Sky Sports (via Football Daily and transcribed by Manchester Evening News), the former Manchester United player revealed his thoughts about Fred and McTominay:"Big, big problems at United. The decision-making and the football intelligence, in particular from Fred - and I've said this for a long time - Fred and McTominay are not good enough. They won't get Manchester United back competing at the top."𝐀𝐅𝐂 𝐀𝐉𝐀𝐗 💎@TheEuropeanLad@UTDTrey Bro you can have Guardiola Klopp Ten Hag Conte and Tuchel managing you together but with Fred & McTominay in midfield you won't get far141701690@UTDTrey Bro you can have Guardiola Klopp Ten Hag Conte and Tuchel managing you together but with Fred & McTominay in midfield you won't get far"We see it week in, week out. [They are] not up to it. They had to gamble in the second half and Eriksen is probably in his best position when he drops back and he's picking up people, but [that decision comes] too little too late."The Old Trafford faithful will certainly be in agreement with Roy Keane, as they were understandably concerned about 'McFred' when United released the lineup. Erik ten Hag was not vindicated for choosing the midfield duo to start the offseason, as the fans' concerns came to light even before the first half ended.Football Daily@footballdaily🗣 "Big, big problems at United."Roy Keane says that Erik ten Hag has a big job to sort at Manchester United51780🗣 "Big, big problems at United."Roy Keane says that Erik ten Hag has a big job to sort at Manchester United https://t.co/2rYOExsJLNScott McTominay's poor performance drew the ire of the fans, and the midfielder was thankfully substituted in the second half for Donny van de Beek.
