Liverpool return to the top of the Premier League table following Sunday afternoon’s 0-0 draw against rivals Manchester United.However, Jurgen Klopp will feel this was a huge missed opportunity for his team after United were forced to make three substitutions before half-time due to injuries.The Red Devils were already without Nemanja Matic due to an injury in training. Scott McTominay made a rare start in central midfield.Ander Herrera, Juan Mata and Jesse Lingard were all forced off before the half-time break following a bizarre opening 45 minutes at Old Trafford.Liverpool forward Roberto Firmino, meanwhile, also picked up an injury and was replaced by Daniel Sturridge.Despite all of the pre-match build-up, this was a game that failed to live up the hype, partly because of those four first-half changes.It never really got going and clear-cut chances were few and far between.There was a rather curious incident in the second half, however, involving Jordan Henderson and Klopp.Klopp decided to substitute his captain, sending on Xherdan Shaqiri in his place, and Henderson failed to shake his manager’s hand as he made his way off the pitch.He seemed a little annoyed that he’d been withdrawn at such a crucial stage of the match.This reaction appeared to anger Klopp, who was filmed by Sky Sports’ cameras moments later reprimanding his skipper for failing to shake his hand.He could also be heard saying: "You didn't clap my hand".Watch the incident here…

Klopp could have spoken with Henderson in private, but clearly wanted to address the issue there and then.

He made it clear that players need to show him respect, regardless of the decisions he makes.

Here’s how football fans on social media reacted to the incident…

Liverpool will aim to get back to winning ways when they face Watford on Wednesday evening.

They then take on Everton in the Merseyside derby next weekend.
