Aguero is the most prolific overseas player in the history of the competition after his hat-trick for Manchester City at Aston Villa on Sunday took to him to 177 goals – beyond Thierry Henry's mark of 175.
Gabriel said: "He is a great guy and a legend of course. I'm in the same position so I have to learn.
"Of course I think our football is different - he is more of a striker, more of a finisher. We work together, every single day. I can learn from him. So that's what I have to do.
"He's a legend of the Premier League, a legend of the club - when he goes to the pitch he scores always.
"I go to the pitch to enjoy my football. If I have the opportunity to break [the record] of course I want to. But I want to go to the pitch to enjoy football and to score goals."
