Draw is a fair result to be honest. It's Saka vs. Son and both parties were lucky in their goals. Too many defensive personal mistakes happened. Nketiah was lucky to finish without red card. The result is acceptable for both teams, their unbeaten series are going on. If we were to list the matches in which it's possible not to get 3 points during the season, both sides would find 1 point in this match acceptable.
Overall the game was evenly matched, so I also agree that it was a fair result for both clubs. Arsenal and Tottenham I think played well and even though Arsenal could take the lead, Tottenham could come back, and even the second goal that Arsenal scored could be answered in a very short period of time. Son H Min became a very influential player in this match, yes the 2 goals he created forced Arsenal to only be able to reach a draw at their own headquarters. Both clubs both do not want to lose points.
