Manchester United suffered another heavy defeat to their great rivals Liverpool on Tuesday evening to leave their top four hopes hanging by a thread.Ralf Ragnick's side were completely outclassed by the Reds, who ran out 4-0 winners at Anfield thanks to a brace from Mohamed Salah, as well as strikes from Sadio Mane and Luis Diaz.In truth, it could have been a much worse scoreline for the visitors, having only had two shots in the 90 minutes, compared to Liverpool's 14. According to PremierLeague.com, Jurgen Klopp's side had 72% of the possession, as well completing 879 passes, compared to United's 349.Dominic King@DominicKing_DMThere will be some young fans who watched this game tonight and think what Liverpool have done here, and over this season, is normal.

He showed delight that someone from Manchester United was running around and closing people down, a rare sighting in this particular clash.Hannibal joined United for £9 million in 2019 from Monaco, according to Transfermarkt. The young midfielder was forced to wait for his opportunity, but Neville was impressed with the teenager's strong tackle on Keita. The tackle seemed to fire up his teammates near the end of the encounter when they were already well beaten.As per The Mirror, he said:"It takes a young kid to come on and show the rest of them how to sprint for the ball and put a challenge in.I'm actually proud of him! Maybe he doesn't like the idea of Liverpool players passing it round him. I wish the rest of them were the same."Ragnick's side have dropped down to sixth following a heavy defeat, still three points behind Tottenham. The Lilywhites are in fourth position, occupying the Premier League's final Champions League spot. Spurs, though, have a game in hand and have a far superior goal difference.Richard Jolly 🇺🇦@RichJollyBig day for everyone who has crossed the Alps on an elephant as Hannibal Mejbri becomes the first Hannibal to play in the Premier League.9:47 PM · Apr 19, 202247236Big day for everyone who has crossed the Alps on an elephant as Hannibal Mejbri becomes the first Hannibal to play in the Premier League.
