No clubs in the top 4 can win the match this week, so it is not so bad result for Man United. They are still in 3rd place and only 2 points behind from Man City. But Man United can't lose points again if they want to overtake Man City, they must play more consistent in the next matches. Sure, without Casemiro and Eriksen, Man United looks weaker, especially in the midfield line. So, I assume Man United will play more consitently when Casemiro and Eriksen are available again. And I think Martial is better than Weghorst, so Ten Hag should prioritize Martial to play more as the main striker.
Yes, at least, they were quite the same between drawn or lost, so the different points were not really high. Man City was not really surprising because they faced Tottenham which is a strong squad. But for Arsenal, it is quite surprising with the result because of the loss of Arsenal itself.
Btw, actually, man United won the match in match 22 vs Crystal Palace, and the last match was the replacement of the 8th match that was delayed. But it is the same with the result. Now the difference in the points is not really far, so this will be still difficult to determine which club will be the champion this season.
