#1 Their counter-attacking brilliance
If the trio were more clinical, they would have easily combined to score five goals - at the very least. Salah, for last season's heroics, got frustrated too quickly in his pursuit of a goal.
Had he been more patient and unselfish in-front of goal, Liverpool would have confirmed all three points long before the full-time whistle. Only Harry Kane (22) had fewer touches on the ball than him, yet he took four shots and really should have been more potent with his chances.
Mané's decision-making meanwhile, was lacking. He probed both in and around the Spurs box often but he'd either been fouled (game-high 6 times!) or lost the ball by the time an opportunity had opened up.
Firmino, as previously stated, did the dirty work that never really shows up in the match stats. His relentless pressing game and intelligence out of possession meant the trio were increasingly dangerous against Tottenham's backline.
