Higuain hit a hat-trick on Sunday for the 7-0 win over Sassuolo.
“We prepared the match to press them from the first minute," Higuain told JTV.
“[Coach Max] Allegri asked us to be aggressive because Sassuolo are a very technical team, but scoring four goals in the first half helped us direct the game.
“There are still a lot of games to go, but we're on the right path.
“The Fiorentina game which is coming up on Friday is very important, we absolute cannot afford to think about the Champions League.
“It would be a huge error, concentration, ruthlessness and a sense of responsibility are key to our approach.
“There are still a lot of games to go until the head-to-head game with Napoli, so we need to face every match with the utmost concentration.
“Tottenham? We'll prepare for that game starting from Saturday morning, in competitions like that it doesn't change much whether you're at home or away first.
“The important thing for Tuesday will be to try and score, not concede, then play for it in London."
