The Englishman scored twice in quick succession on his way to earning a 9.0 Flashscore player rating, the highest of anyone across the weekend's action.
Maddison first opened the scoring with a superb first-time effort from close range before latching onto a Heung-min Son pass just minutes later and chipping a brilliant finish in for his second.
Spurs went on to score another two goals and record a shock 4-0 win over the current champions - with Maddison central to their success.
