Manchester United suffered their second defeat of the Premier League campaign against arch-rivals Liverpool on Sunday.
The Red Devils started off brilliantly at Old Trafford and they had close to 65 percent possession in the opening 30 minutes.
However, it was Liverpool who broke the deadlock in the 35th minute after Casemiro gifted cheap possession in the lead-up.
With Diogo Dalot higher up the field, Mohamed Salah delivered a lovely cross beyond the central defence for Luis Diaz to head home.
