Manchester United struck twice past the 90th minute to defeat West Ham United 3-1 in the fifth round of the FA Cup at Old Trafford. Fans have taken to Twitter to slam the duo Harry Maguire and Scott McTominay for their lackluster performances tonight (Thursday, March 1).Manchester United's confidence would have been high coming into tonight's fixture, having won the Carabao Cup on Sunday (February 26), following their 2-0 victory over Newcastle United.United manager Erik ten Hag made several changes to his starting XI. The likes of Harry Maguire, Victor Lindelof, Scott McTominay, and Marcel Sabitzer were given opportunities to impress.However, Manchester United started slowly in the first-half with both keepers having to make good saves to keep the scores level. The duo of Maguire and McTominay failed to have any sort of impact and were booked before half-time as well. The midfield failed to press effectively, leaving pockets of space for West Ham to exploit.Ten Hag was forced to make an early change, bringing on the in-form Casemiro for McTominay. The Hammers gained the advantage in the 54th minute after Said Benrahma rifled the ball into the top corner.Casemiro seemed to have leveled in the 72nd for the home side, however, he was flagged offside. Five minutes later, the scores were level after Nayef Aguerd's own goal.Alejandro Garnacho and Fred scored in stoppage time to ensure the Red Devils qualified for the quarter-finals of the FA Cup.Manchester United@ManUtdNow THAT's entertainment! 🍿#MUFC || #FACup247174804Now THAT's entertainment! 🍿#MUFC || #FACupManchester United fans were less than happy with the performances of Maguire and McTominay in particular, believing the duo aren't good enough to even make the bench anymore.Here are some reactions:Alex Turk@AlexCTurkThe drop in quality from Casemiro to Scott McTominay is far too steep.

He said:"They have got into some good areas and some good pockets, but what I would say is that it’s lazy sometimes when they get in these good positions. You have got to get players in the box, look! It is just laziness and players watching, you have got to get yourself in there to get yourself a goal - that is what the good players do, they have a hunger and desire to get themselves into the box."Following the game, he also slammed the visitors' poor defending and goalkeeping:"They're having a little discussion, like they're in Starbucks. Come and take people out - come with violence. That's your job!"ITV Football@itvfootball "They're having a little discussion, like they're in Starbucks. Come and take people out - come with violence.
