If Manchester United has players who are able to defend the defense then this is very much considered because their strength is at stake, but it looks like Manchester United in the future have opponents who are not too heavy and they should be able to beat the enemy easily and have to take advantage of this easy opponent. to score a lot of goals.
I think they will struggle if they go against a team with good defense and a strong attack too. Right now I completely agree that their defence seems pretty solid with Martinez and Varane in there but their attack is why I have doubt giving a consistent result. They still need the sharpness in attack and hopefully with Martial return that changes a bit at United.
With Martinez out for the next game in the KO stage we will see how they will be without the Argentina defender, so much quality from a single defender. I was shaky for United last season but he has settled the pressure in the defense. Scoring goals is the next plan those few goals today could not make them go top of the table
