The missing ingredient in Manchester United's domestic season so far is how to hurt the big teams. They failed to score against Chelsea, Arsenal and Manchester City twice, and netted only once against Tottenham before conceding six.
It leaves Ole Gunnar Solskjaer with a dilemma travelling to Anfield as Premier League leaders. If United park the bus and draw another blank, he'll be criticised. If they open up and lose their unbeaten run, he'll be criticised!
I suspect United might try to keep it tight again with Scott McTominay and Fred as twin midfield holders.
