Gonzalez praised the strength of La Liga's fourth-placed side and their Ivorian striker Arouna Kone.
"They do very well on the counterattack," he told the club's official website.
"They are very direct when they get possession and Kone is having a great spell."
But he added: "However, we know how we can hurt them, that we feel more comfortable with the ball on the ground."
The La Liga strugglers, just a point above the relegation zone, signed Senegalese forward Khouma Babacar, 18, on loan from Fiorentina for the rest of the season.
Racing, who picked up a credible 2-2 draw with Valencia last time out, also picked up 22-year-old Villarreal B midfielder Marcos Gullon on an 18-month contract as cover for the departing Greece international Alexandros Tziolis.
Babacar trained with his new team for the first time on Friday but will have to wait for his Racing debut.
However, Gonzalez is delighted with the way Gullon has settled quickly and will travel.
Levante suffered a surprised 2-1 reverse to Getafe in their last game and are without a win in 2012 but are still in the hunt for for a Champions League place.
Coach Juan Ignacio Martinez has a full squad from which to pick with the exception of longer-time absentees Keylor Navas, Sergio Garabato, Juanlu Gomez and Jose Barkero, although the latter has resumed training with the first team.
