Aguero has recently been strongly linked with a big-money move to Spanish giants Real Madrid.
“The truth is that I’m happy,” Aguero is quoted as saying in the Daily Mirror.
“The club treats me very well. It’s very calm – it’s different to being in Spain or Argentina.
“The only thing I do is enjoy football, rest, be at home and go out to walk around or eat in peace.”
Aguero added: “You are always improving. English football, for example, being so fast, it allows you to develop your concentration and refine your technique.
“So every day you’re learning and I feel that I still have plenty to learn. I have always said that, in every match, watching or training, you learn things. It’s like in any job, you know what to do or not to do.”
