Manchester City will only sell Sergio Aguero for a record fee.
The Daily Express says Aguero, who joined City from Real's Madrid rivals Atletico three years ago, has three more years on his contract and club sources insists they are not interested in selling a player who finished as their leading scorer despite missing half the season with various injuries.
A City insider said: "We would have to be offered a staggering sum - similar to the £85m Real paid for Gareth Bale last summer - for us to even entertain thoughts of selling Sergio. He is that valuable to us."
