All the latest news, views and transfer stories from the Etihad...
A French youth international, the 19-year-old midfielder arrived at the Etihad Stadium in 2013 from Ligue 1 side Lorient and has since established himself as a key member of Patrick Vieira’s Elite Development Squad, making 35 appearances during the 2013-14 season.
He could make his debut for the Whites in their Championship match at Brighton & Hove Albion on Saturday, with nine further fixtures scheduled between now and the end of January.
In other transfer-related news, Monaco vice-chairman Vadim Vasilyev has rejected talk of a possible move to City for left-back Layvin Kurzawa, following reports that the France international met with club officials in Manchester on Tuesday night.
"Kurzawa? He is a Monaco player, there is no doubt about that," he told reporters on Wednesday. "I don’t have to make any other comment about those rumours."
Kurzawa, 22, reportedly flew into Manchester as a guest of City's for the Champions League match against Bayern Munich, but was prevented from attending the game at the last minute by the French club, according to L'Equipe.
Instead, he was forced to watch the 3-2 comeback win on television, but still would have no doubt been blown away by the performance of hat-trick hero Sergio Aguero.
The Argentine striker's teammates certainly were, with right-back Bacary Sagna admitting the rest of the squad must follow the example set by their leading man.
"He's bringing the team up at the moment and I think we all have to follow his steps because he shows the right example,” the right-back told the Daily Mirror.
“He keeps fighting and in front of goal he's just clinical, so as long as he keeps scoring we can be happy.”
That sentiment was echoed by loan star Frank Lampard, who believes his colleague to be one of the world's best players, alongside the like of Cristiano Ronaldo and Lionel Messi.
"If he can carry on with this form, doing it week in and week out, which he is doing, then people will talk about him in the same breath as them," the former Chelsea midfielder told Sky Sports.
“I haven’t been fortunate enough to play with those two, but in terms of ability he’s right up there.
“He’s top of the world football strikers. When you have people like that it makes things easier, because Sergio takes the majority of his chances – he took every one of his chances against Bayern.
“I’m fortunate enough to have played with Didier Drogba, who for me was the greatest striker, but it’s very hard to compare those two because their style is so different.
“But in terms of pure finishing, electric pace, in my first few days training here my friends and other people were asking, ‘who does this or that in training?’ and I said, ‘this Aguero is just different class’. He’s proved that. He can’t stop scoring.”
