And another wrote: ‘Salah fuming at the end looked in tears.”
Salah is joint top scorer in the Premier League this season with 17 goals, but has often appeared miserable after scoring.
The Egypt star was scintillating last season and has not quite hit those heights this term despite his impressive goal haul.
And his hooking late on at Manchester United when Liverpool were searching for goal showed his luck was not in today.

Ole Gunnar Solskjaer credited Luke Shaw with keeping him quiet.
He said: “When they need a goal and they take Mohamed Salah off you know Luke Shaw has played a good game."
Klopp though was keen to move on after moving top of the table, a point clear of Manchester City after the same number of games.
“It was a strange game,” he said.
“We started really well. All the injuries in the game obviously cost us rhythm. It happened to us with 'Bobby' and that was a catastrophe.

Mohamed Salah was hooked in the second half against Manchester United (Image: GETTY)
"United played with a completely new midfield and three up front. We lost our rhythm and couldn't get it back.
"It was a game without a lot of highlights - it was intense. On days when United are beatable you have to do it and we didn't do it.
"We have a point more and Wednesday is out next game."
Salah is likely to be involved when Liverpool face Watford at home on Wednesday night as they look to maintain top spot.
City are also in action at home to West Ham and will be waiting should the Reds slip up.

James Milner admitted they weren’t good enough today but did highlight one pleasing thing.
"A clean sheet is pleasing because it's not an easy place to come,” he said. “We didn't get many chances as we would have liked and we're disappointed not to win the game.
"Hopefully it's a good point come the end of the season. i just don't think we were good enough with our movements or final ball.
"United are a confident team and well organised. There's a long way to go.
"We have to look where we can improve when we have got the ball."
