Jurgen Klopp's side went on to win the game 2-0 at Anfield.
The Reds were 2-0 winners at Anfield on Thursday in the hotly anticipated clash, with Daniel Sturridge’s penalty setting them on their way to victory.
There was much debate about whether it was a penalty though, with many arguing Memphis Depay was harshly treated by the referee for the foul on Nathaniel Clyne.
Two who believed it was harsh were former United stars Ferdinand and Scholes, who said as much while commentating on BT Sport.
“I just think anywhere else on the park that is isn’t given as a free kick and I don’t think it warrants a penalty,” Ferdinand said.
“I don’t even think it’s a foul anywhere on the pitch, I don’t think it’s a foul. If that’s against me in a game, I’m disappointed,” added Scholes.
While United may feel harshly done by over the penalty, they arguably didn’t do enough in the game to win it regardless.
Not for the first time this season, Louis Van Gaal’s side looked toothless in attack and failed to seriously test Simon Mignolet in the entirety of the game.
In contrast, Liverpool were dangerous throughout, forcing David De Gea into several top saves, with the Spaniard ultimately the only factor that stopped it being a rout for Klopp’s side.
That makes United’s argument somewhat irrelevant, although they will feel wronged by the decision nonetheless.
