The worrying thing for Manchester United is that while Manchester City had moments of brilliance at Old Trafford, they did not really have to do much to beat them 3-0.
That is the kind of resilient and tenacious performance I was expecting from them this time too, but when I saw the United line-up I was worried for them. I know Erik ten Hag has some injuries to contend with, but it does not seem like there are enough repercussions for some United players if their intensity is not at the required level.
On Sunday, they did win the ball back in good areas in the first half, and forced City into mistakes, but you have to maintain that for 90 minutes. They couldn't, and we saw what happened. Against United, they knew when to play through the lines, when to clear their lines, when to go for goal and when to come back and frustrate the opposition, until the time was right to hurt them.
