Paul Pogba is poised to miss Manchester United's clash against Liverpool with an injury. He suffered a gash in his leg in training on Friday and was going to be put through a late fitness test today before the lineups were announced.However, a fitness test will not be required as the Frenchman has been officially ruled out of Saturday's lunchtime kickoff against United's bitter rivals. This is a huge blow for the Red Devils as it leaves Jose Mourinho with limited options in midfield and also on the bench.Marouane Fellaini has returned to the United squad but has started only once since November. Ander Herrera is also ruled out with a hamstring injury which may prompt the Portuguese boss to start with club captain Michael Carrick, who has not started a Premier League game since last season.Another blow for Mourinho's side is that Anthony Martial will also be unavailable following a thigh injury which caused him to miss the game on Monday night against Crystal Palace.Here's how Twitter reacted:Man Utd lacking ideas big time & #pogba has gave the ball away more times than me on FIFA18— Tony Wilson (@toblarone77) March 5, 2018#Pogba out injured.
