What I saw was that Man United played badly in this match, so it could be considered that they were very lucky to get a draw. If we look at the possession of the ball and how Tottenham really dominated the game, as if this was an away match for Man United, though we all know the match was held at Old Trafford. As a team, Man United doesn't have a good rhythm and they also look very sluggish on the pitch (only a few players seem to have a high fighting spirit : Hojlund, Garnacho, and Bruno Fernandes)
Manchester United had a strong opponent this week and of course a draw was very good for them. Tottenham this season, if compared with Manchester United, Tottenham is definitely much stronger than them. In this match, Tottenham performance was more impressive because they were able to balance their strengths at home to their opponents. I think Manchester united weakness is none other than because they didn't focus on playing more defensively when they took the lead early.
An additional 1 point from this match made Tottenham equalize their points tally with Arsenal. But Arsenal still has one game for week 21 so Arsenal has the opportunity to get away from tottenham pressure. Tottenham continues to put pressure on the top 4 ranked teams because if they fail to achieve maximum results then tottenham will take advantage of the opportunity to return to the top 4 rankings.
