Mexico City: Mexican Formula 1 driver Sergio "Checo" Perez said that his aspiration is to become part of a team led by a champion such as Lewis Hamilton, Sebastian Vettel or Fernando Alonso. "I would be delighted to be with world champions, to be a teammate of Hamilton, Vettel or Alonso," Perez said at a press conference in Mexico City on Wednesday, reports Efe. "In Formula 1 there is such a difference among teams and cars that your best touchstone is your teammate and to have a world champion as touchstone is always good," the Guadalajara native said ahead of this weekend's Mexico Grand Prix.
