What is the story?Manchester United have now lost six of their last eight matches in all competitions. Moreover, the club endured a forgettable evening at Goodison Park as Ole Gunnar Solskjaer's men recorded their poorest performance under the 46-year-old Norwegian.Fans reacted angrily to United's display, demanding that the club shows the door to a few star players from their club. Frustrated United fans want Serbian defensive midfielder, Nemanja Matic out during the summer transfer as his body language on the field doesn't suit a club like Manchester United.In case you didn't know...Everton outplayed Manchester United in their weekend's Premier League fixture on Sunday. The 4-0 scoreline was enough to suggest how poor the Manchester United players were on the day. The goals by Richarlison, Gylfi Sigurðsson, Lucas Digne and Theo Walcott exposed United's defensive frailties under the current coach Solskjaer.Matic's poor marking allowed Iceland's Gylfi Sigurðsson to score Everton's second, a wonderful strike from distance. Matic failed to close down the star midfielder and allowed him to take a shot from about 35 yards out. As a result, United conceded their second goal of the match.The heart of the matter...After the awful 4-0 defeat against the Merseyside club, disappointed Manchester United fans vented out against Nemanja Matic on social media.Matic is stealing a living at Manchester United. He genuinely just watched Sigurdsson strike it, he didn't close him down at all. That was frustrating to watch.— Devils of United (@DevilsOfUnited) April 21, 2019Another United fan added,People blaming De Gea for that second Everton goal? Did you lot not see Matic walking to try and block the ball. Disgraceful, get out of our club.— Aidan Walsh 🔰 (@AidanWalshMUFC) April 21, 2019Fans also started to give solutions as one wrote,YOUNG, lingard, Matic, smalling, Jones the 5 worst players in the team. Sell them first then move on to the likes of Sanchez, Herrera, Fred, mata, Rojo, darmian.If we get replacements for martial and lukaku then sell them too, the rest can be replaced with youth. #mufc #evemun— Ricky Davies (@RickyDavies17) April 21, 2019A fellow United fan then said,Sell Matic @ManUtd !!!!!— ANGEL GOMES (@RbnPlay_) April 21, 2019A disappointed fan further commented:#MUFC this summer we need to sell/replace if we want to have any chance at winning somethingLukakuMaticSanchezLingard MataSmalling YoungJones Pereira Darmian FredRojo— FatalFlesh (@FatalFlesh13) April 21, 2019Another supporter added,Matic thought it was a training drill ffs. Shocking defending.— RG (@registability) April 21, 2019Speaking to Sky after the match, Manchester United legend Gary Neville lambasted United for their pathetic display against Everton:“Yeah I’m simmering to be honest with you and my blood’s about to boil. I didn’t buy into that these players were always fantastic when they started to win for Ole in those two, three months."“If you think about the game we did against Liverpool a few weeks ago where everything was perfect, Ole had got the players playing again, Jose Mourinho was a bump, and basically it was just down to Jose."He further made these comments,"Now we’re seeing what Ole talked about on Friday is that there is a reality check and I think it’s a reality check for all of us."“What Louis [Saha] alludes to there about players not running back properly, I went to Barcelona on Wednesday night and watched the game and I saw players pretending to run back.""You know, making it look like they’re running back quickly, doing that little jogging one. Oh it’s rubbish."He concluded by saying,“And I think what we’re seeing now is what the players are."What's next?Manchester United, who are in the 6th position in Premier League points table with 64 points from 34 games, will host Pep Guardiola's Manchester City on Wednesday night. Manchester United have to win that match to stay in the hunt for the remaining two Champions League places.
