The former City star revealed that back in 2009 - while he was still at Atletico Madrid - Chelsea had expressed their desire to sign him. The striker, however, continued at the Spanish club for two more years before joining the Manchester-based club.

The Blues became interested in the player after their clash against Atletico in the Champions League in November 2009, when a young Aguero netted a brace in a 2-2 draw. The Argentine at that point, did not consider the offer as he still had three years left in his existing deal.

Speaking to The Club YouTube channel, the ex-Argentina international said, "After that game, maybe two months after, my agent said to me: 'Chelsea are interested'. I had just three years at Atletico Madrid. I mean, I loved the Premier League, to play there, but Chelsea were never interested after. At first, yes, but then my agent said: 'Okay, maybe not'."

He further revealed what Stamford Bridge legend Frank Lampard told him after the English midfielder joined City in 2014 on a short-term deal.

He added, "I spoke about that with Frank Lampard because Frank Lampard played at Manchester City. He said when I played against him, he told the staff at Chelsea to sign Aguero."
