Even though Manchester United could not win , their performance was good. And if this run continues , if they can strengthen the defense a little, then I think this team can definitely make it to the top 5 of the table. Arsenal played defensively in this match. After taking the lead in just 13 minutes, their target was to end the match 1- 0. Arsenal secured 3 points from the match, but Manchester united players dominated the entire match. Manchester united seems to be stronger and more organized this season compared to the last season.
Man U has the heart of the people after a terrible underdog status in the last season. We can't judge by a single game how tough the team have become, despite losing their first match, the only task for Amorim this season is to clear or remove the memories of last season with a more responsive performance. Then switch tactical approaches, because every other manager watched them and would play the red devils according to the tactics they displayed in previous games. If Amorim can interchange his strategies, coupled with the strength of his men, they'll be no problem for the reds at hitting the top 5 spot.
I think Amorim did not make any mistakes in his tactics in this match. He should be happy with the performance of his players but his match could be a lesson. Most of the polls had Manchester United as the favourites and they played well but didn't win. Sometime this is happens when a good team is not lucky and they lose. I watched the match and I thought they played much better than Arsenal. Arsenal defence is very strong which is evident from this match. Despite creating chances and attacking many times Manchester's forwards failed to find the net.
