Former Chelsea captain John Terry didn't back Blues' move to sign Sergio Aguero
Chelsea chased Argentina forward Sergio Aguero relentlessly back in 2009 when he was back at Atletico Madrid in Spain.
The summer of 2009, and Chelsea were looking for the 'next big thing' and Carlo Ancelotti was keen on bringing Aguero to Stamford Bridge.
"I like him," Carlo Ancelotti said on the Argentine attacker. "I think Aguero can play with Drogba, for sure."
Atletico Madrid wanted in excess of £40 million for their prized-asset, but Chelsea and Roman Abramovich weren't convinced on paying the amount the Spanish side wanted.
The January transfer window came and still Chelsea couldn't come to an agreement.
But according to The Athletic, former Chelsea captain John Terry passed his thoughts onto the Blues' hierarchy in that he wasn't keen on the Argentine.
Terry wasn't 'overly impressed' with Aguero's movement, and preferred forward David Villa as an alternative option.
But in the summer of 2010, Chelsea were still interested in Sergio Aguero, and so was the forward.
"Chelsea are a great club," he said. "They have become one of the most feared in Europe over recent years. I look at players like Drogba and Lampard and they have been — and still are — the best players in their positions in the world. I could really learn from players like that, there is no doubt.
“London would be a really amazing city to live in as well, myself and my wife could be really happy there. Carlos Tevez is doing really well at Manchester City but, for me, it is about joining a club who are ready to challenge for honours. City are not ready yet."
But Chelsea continued to fall short of the valuation, even with a buy-out clause of £28.7 million, the Blues only made bids of up to £22 million.
Since then, the 31-year-old has hit new levels in the Premier League with Manchester City - scoring on 173 occasions in the league in 250 appearances.
Four Premier Leagues and a golden boot in the nine seasons at the Etihad, Chelsea would have been itching for a forward with a natural instinct for goal like Sergio Aguero over the years since the departure of Didier Drogba.
