Pep Guardiola urged his players to finish the season strongly, starting with their home league fixture against relegation strugglers Swansea City on Sunday.
However, the head coach need not have worried as the 'Sky Blues' came out the blocks in stereotypically dominant fashion and would go on to control the game for the whole 90 minutes.
The opening stages lacked any clear-cut opportunities but it wouldn't be long after the 10-minute mark that City would break the deadlock.
Kevin De Bruyne found Raheem Sterling in the box who proceeded to play through David Silva. The Spaniard flung his first-touch of the ball into the air but then comfortably fired it past opposing goalkeeper Lukasz Fabianski to make it 1-0.
Swansea's woes would be compounded just four minutes later when Sterling doubled City's advantage.
Fabian Delph and David Silva linked up seemlessly with a brilliant one-two on the left wing to give the Englishman space to fire in a cross to his compatriot in the box. It was easy from there for Sterling who steered the ball into an empty goal.
Fabianski would be kept busy all game and was forced into a double save in the 32nd minute.
De Bruyne's curling shot required a full-stretch save but the Polish goalkeeper could only parry the ball into the path of Sterling. Thankfully, Fabianski was over quick to guard his near post from another shot but the offside flag meant that it wouldn't have counted regardless.
The game was so one-sided that Swansea had to wait until just before the break to have their first crack on goal, although Alfie Mawson's long-range effort barely troubled Ederson, who could have spent the half in the stands.
Despite their dominace, illustrated through 86 per cent possession and 582 completed passes, City would only go into half-time with a two-goal lead. Though they would soon extend that in the second 45 minutes.

De Bruyne gave glimpses of his finishing when he found the side-netting with a venomous shot five minutes after the break, but the Belgian would write his name on the scoresheet shortly after with a wonder goal.
The 'Sky Blues' won the ball in midfield, giving it to De Bruyne. The 26-year-old then ran at goal for a few metres before opening his body just outside the box to fire a thunderous shot across the face of goal, past a helpless Fabianski, to nestle into the far corner.
Swansea's day would go from bad to worse when Federico Fernandez took out Sterling with a late challenge in the box to gift the home side a penalty.
Gabriel Jesus stepped up to take the spot-kick but his effort smacked the post, flying out to Bernardo Silva who fired home the rebound to bring up City's fourth of the game.
Substitutions saw the game dip into a lull but the Etihad would erupt in the 74th minute as Benjamin Mendy entered the pitch in place of Delph, the defender making his first appearance since sustaining a serious injury in September.

From there, City continued their dominance and Jesus would finally score just before the end as he directed a perfectly-dinked ball by Yaya Toure into the far corner with his head, finishing off the champion's masterclass performance.
As the full-time whistle rang out in Manchester, the home crowd invaded the pitch, surrounding Mendy as they finally celebrated their Premier League title with the players.
The win moves City onto 90 points with four games remaining whilst Swansea languish one place above the drop zone as the relegation battle heats up in England's top division.
