​Chelsea legend John Terry had demanded his club back then to back off from signing Sergio Aguero before ​Manchester City snapped up the to-be ​Premier League great.

The 31-year-old Argentine striker left ​Atletico Madrid in 2011 to complete a sensational £35m move to City. 

According to The Athletic, the Blues had ​made their first enquiry about the Argentina international two years before his transfer to the blue side of Manchester.

However, the Londoners were not ready to agree on the transfer price asked by Atletico as well as the salary demanded by the Argentinean.

The report then goes on to state that Terry, who was a significant influence at the club at that time reportedly blocked the deal from going ahead. 

It has been further revealed that Terry wasn't impressed with Aguero's movement having played against him whilst he was still in Madrid. Instead, Terry, who is now the assistant head coach at Aston Villa, wanted Chelsea to cool their interest in Aguero and make a move for David Villa.

Furthermore, while Chelsea didn't make their initial move for Aguero after Terry's involvement, they did reignite their interest in the Argentine striker before he signed for City. Since then, Aguero has become City's all-time record scorer and the sixth-highest scorer in the Premier League's history.
