The Mexico international has struggled for regular game time following his €11 million move to the Vicente Calderon during the summer.
Jimenez concedes he faces a difficult task in living up to the standards set by some of Atleti's recent forwards, but insists he is blooming as a footballer under Diego Simeone and is fully capable of leaving his own legacy at the club.
"It's not easy trying to match the likes of Diego Forlan, Diego Costa and Radamel Falcao," the 23-year-old told AS.
"They are all great players who played their role in the team and delivered the goods when they came here.
"Even so, I have to make my own history and do what I came here to do - which is score goals.
"I'm learning new things every day and that's crucial as you always need to take advice from the best to keep growing as a player.
"There are things I need to improve upon and I know that's not easy because there are a lot of other players who want the same."
