Heading into the game, Liverpool were heavy favourites.
A win would have equalled a Premier League record of 18 consecutive victories, while United entered the game just one point above the relegation zone.
But the Reds have a pretty wretched recent record at Old Trafford and produced a disappointing performance.
But they will feel hard done by that Marcus Rashford’s opener was allowed to stand after Divock Origi was fouled in the build-up.

However, Adam Lallana grabbed a late equaliser to maintain his side’s unbeaten start to the season and extend their lead at the top of the Premier League to six points.
One point gained or two points dropped?
That probably won’t become clear until the end of the season but one player that clearly wasn’t satisfied despite Lallana’s leveller was Sadio Mane.
Images have emerged of Mane pulling Lallana away from the celebrations in an attempt to get the match restarted as soon as possible.
Mane knew a draw wasn’t a great result for Liverpool and, with five minutes remaining, felt his side could go on to win the match.
Ultimately, they couldn’t quite force a winner and had to settle for a point.
After the match Jurgen Klopp took aim at United’s tactics, suggesting that all they wanted to do was defend for 90 minutes.
“Whoever said before the game that this game is always built up like a mountain and stuff like that and then we come here and they only have to defend,” the German said.
So one day I will really wait for the day when they have to make the game against us and we defend – and let’s see how that is.
“Since I’ve been in England it’s pretty much been like that. We come here put it all together, attitude, tactical defensive shapes.
“Eight players defending, with the quality of Man United, it’s not easy. We expect to play much better than we did today.”
