It's just the beginning of the season, we can't conclude anything yet, but as seen in Manchester United's performance in the first week, I think they have played a little better, even though the final result is still a loss, but at least there is progress from the team's game, so for this season anything is still possible and I will not underestimate Manchester United this season.
Losing by one goal against a strong team is very common for a team that slumped last season and is trying to bounce back this season. And I think Manchester United needs to make more significant changes in other matches this season, because every opportunity must be capitalized on to win, even by a small margin. I also wouldn't say Manchester United is in good shape, despite the slight changes in their performance in their first match of the season. Because that's far from enough for them, who are working on improving all aspects to become better than before.
The truth is that many persons were so impressed with their performance due to the fact that its been long we actually saw any Manchester United team play any good football like this and thats why despite the fact that they lost the fans were not so disappointed and even i think they were all impressed to how they even played and well but the truth is that if they want to go far in this season campaign then capitalisation of their chances would come in handy and not just creating them without converting it.
