When they managed to carve out a chance, it tended to fall to the wrong people. I think it is disappointing for Liverpool to lose considering United made eight changes to their team from the Manchester City defeat last Sunday.
Luis Suarez did well on his return to action. I think Suarez only knows one way of playing which is full out. You could see he lacked a bit of sharpness which is understandable.
You can see what Suarez is going to add to the team immediately. I'm not sure how successful his relationship will be with Daniel Sturridge up front, but he is certainly looking like the player we know he is.
I quite like the system: 3-5-2 keeps Suarez and Sturridge quite central, and suits them both.
They don't spend a lot of time drifting away from goal. It would also be perfect for Philippe Coutinho to just slot back in behind them as that attacking midfielder if Rodgers wanted to play that system longer term.
Suarez likes to drop in to get the ball to feet while Sturridge prefers to race in between the centre halves and full-backs. When you look at it, they should be perfect playing together.
If you have a player of Suarez's talent, it doesn't take much to welcome him back in. I'm sure the players will be delighted to have a figure of that talent back in the fold.
Liverpool were very strong in the summer by refusing to sell him, but now the club have to convince Suarez that he can achieve what he wants by staying at Anfield.
I think a player like Suarez wants to play in the Champions League, and he wants a club with a genuine chance of winning it.
I think his talent deserves that. I think there will be some questions to be answer a year from now if Liverpool aren't in the Champions League, but for the time being he is there.
Rodgers will be happy enough with the performance if not the result against United, but worried about marking from set-pieces and failing to score any goals in the second half of matches. These are things to work on.
The defence has to be a concern for Liverpool. Rodgers is putting it down to individual errors, but they could be very costly over the season.
Mamadou Sakho is a bit erratic in defending. He is a bit loose with his passing, but he is quick and just needs to settle down. He is physically strong enough to play in the Premier League.
Champions League qualification has to be the aim for Liverpool with the amount of investment they have made.
They might miss out because there are six strong teams there, but you would have to think Liverpool will be there or thereabouts right to the end.
Manchester City produced an impressive display against United on Sunday, but that was the best team performance of the season. I think you could pick holes in all of the challengers, including City.
Every team has their flaws. Liverpool are not miles away, but they have a run of winnable games in October. They must look to win two or three of them to breed confidence.
