After failing to muster a single shot in the first half, City also made history by becoming the first side to ever exit the Champions League in a knockout tie after scoring five goals in the first-leg.
City recovered from twice falling behind in the first leg, but the opening goal emboldened Monaco as Germain unleashed a searing strike from distance that zipped not too far over.
City had prevailed in the first leg because, ultimately, it was able to dominate possession and move Monaco's holding midfielders out of position, but here it never had enough of the ball to do that, its own defensive shortcomings being brutally exposed.
"When you are going to play the "eighth-finals" of the Champions League in Monaco, just the desire to be in the quarter-finals will put our little exhausted situation away". Giving them support from the wing will be the fleet-footed Thomas Lemar and between the three of them, they can easily overturn Monaco's deficit in the tie. City's defence barely got any respite and the entire side was outclassed by the attack-minded Monaco, who had scored 123 goals this season before welcoming Guardiola's men to Stade Louis II.
I want to note that Monaco for the entire current season lost in their native walls, only one match, which happened in mid-December in the league from Lyon.
And it is their array of attacking talent, and the fearlessness of their youthful squad, that give them hope of upsetting Manchester City in their Round-of-16, second-leg clash tomorrow morning (Singapore time). It was young star Kylian Mbappe with his 11th goal in as many matches, finishing at the front post just eight minutes in.
What did the French press make of the first game and how do they rate Monaco's chances on Wednesday? Atletico lead the fixture 4-2 with all four being away goals.
I can not think of a brighter young talent in France right and the chances are that if somebody gives you the name of a player other than Mbappe, it might well be Thomas Lemar, Tiemoue Bakayoko or even Benjamin Mendy.
Pep Guardiola opted start Yaya Toure on the bench and went for an attacking by playing David Silva, Kevin de Bruyne and only one holding midfielder. "What you have to do is go to score goals".
I doubt any of that will have much of an influence on the immediate future of the club and though I am not going to invest, a routine home success is obvious as the evidence clearly stacks up.
