Chelsea won with a reasonable score because it was in accordance with the quality of the game given by the entire team, not because of the referee's help so that Chelsea could win or not because of a robbery. If VAR had not canceled Chelsea's two goals, a score above 4 could have happened.
Spurs ought to express gratitude to Guglielmo Vicario for a job well done despite their immense defeats; the goalkeeper did his very best to keep the tie alive but couldn't hang on much longer since Chelsea didn't relent, persistent pressing of the ball to sniff out goals that they earned, making imperative savings on the pitch. I was wondering how 9 men on the field would beat 11 players. There is nothing to be concerned about because the pressure was directed on the defensive lines. VAR ruled out some Chelsea goals owing to probable offsides, which is acceptable.
