Man United's performance is difficult to predict, but most of them always play badly. Especially Onana's blunders, a ball that should have been easy to anticipate but instead he failed.
Likewise in the middle, Bruno did not have a significant impact. I wonder why ETH can give him the confidence to be team captain, even though there are still several players who are tracking to become captain and can make a difference.

In terms of Tottenham's game they were better, they were just unlucky because of the 6 shots on goal only 2 resulted in goals.
Without Son's presence, it would have a very significant impact. Timo Werner making his debut with this assist is enough to prove that he can still compete in the EPL.
