#2 The tactical switch

When Pochettino decided to replace the ineffective Erik Lamela with Son Heung-Min (a surprise exclusion from the starting XI) to add flair upfront, Guardiola was more than ready with his options. The Spaniard quickly introduced Nicolas Otamendi in the 64th minute in place of Leroy Sane who looked a bit off-clour for the Citizens.
Ten minutes later after Sterling had struck City's third, he withdrew Gabriel Jesus for Bernardo Silva, ordering the Englishman to function in the center while Silva took his place on the right.
Initially functioning in 4-3-3, Man City shifted to a 5-3-2 and successfully defended their lead until the final whistle.
The Sky Blues closed down the spaces and allowed no openings for Eriksen, Moura, Son, and Alli to find Kane. They also won the aerial battle against the Lillywhites, winning 14 out of total 23 duels in the air.
Fair enough, paying deserved attention to their defence paid Manchester City wealthy dividends as they went home with a 3-1 win and 3 points in the bag.
