In fact, the then-City manager played a huge part in finally convinving the Argentine striker to ditch Spain for England: "When Roberto Mancini called me, he gave me confidence to come. I always followed English football and I liked it since I was a kid," Aguero explained.
Although the decision was difficult, he doesn't regret it either: "Luckily they treated me well since I arrived and I have adapted well. I am happy with all the good things that I have experienced in these six and half years".
City fans will be glad to hear that their star forward is happy in Manchester too as his 21 league goals this season have helped Pep Guardiola's side to an unprecedented 16-point lead at the top of the Premiership and they could even claim the title in early April if results go their way.
First the squad must negotiate the international break, something that could be easier for Aguero as a nagging knee injury has ruled him out of Argentina's friendly with Italy on Friday.
