The former Barcelona and Tottenham attacker has been starring for the Yellow Submarine this season.
"I came here with the idea of helping the team and I'm doing it," the Mexican told a press conference. "I'm happy and calm. Without doubt, I have never felt so good both physically and personally.
"I think it has been the best start since I became a professional. But it is important to be cautious. You always need to be cautious at the beginning of the season."
