Arsenal did get 1 huge stroke of luck when the penalty wasn't given and Saka went up the other end and scored. Very similar to the infamous Arnold handball when Fabinho scored 30 seconds later. The offside was very close but was the correct call. In theory, that penalty call could have changed the game but in reality Arsenal were clearly the better team and Spurs only got back in the game due to an absolute howler by Raya.Given that we haven't won 7 PL games in a row this season, this might be considered the critical game.
But Spurs weren't that bad vs Arsenal at all. Actually, they could have drawn the game if some refereeing decisions had gone their way. If Spurs beat Burnley and Villa lose/draw vs Liverpool, Spurs will have a (theoretical) chance to make the top 4. West Ham are a completely different case.
Spurs have lost 4 in a row and unlike the past, play a style which should suit us. They will try to go toe to toe with us cos Ange knows no other way. It kinda worked at Etihad (thanks to Tierney) but much earlier in the season when our defence was a mess.
