In the Italian Grand Prix at Monza he passed both drivers who were regarded as the best in Formula One at the time—Juan Manuel Fangio in a Mercedes and Alberto Ascari in a Ferrari—and took the lead. Ascari retired with engine problems, and Moss led until lap 68 when his engine also failed. Fangio took the victory, and Moss pushed his Maserati to the finish line. Neubauer, already impressed when Moss had tested a Mercedes-Benz W196 at Hockenheim, promptly signed him for 1955.
