Anzar, a left-footed wing half with a ferocious shot, played a total of 169 games and scored 118 goals for Olympique de Marseille.

On 22 May 1943, during the cup final against Bordeaux, Aznar scored a 31st-minute goal which made a hole in the netting (which he claimed was more a sign of the poor equipment available at that time, rather than the power of his shot).

On 4 October 1942, Aznar set an unofficial record by scoring 9 goals in one match against Avignon Foot 84 (Marseille won 20–2), despite being substituted in the 66th minute due to injury.

Manu, whose career like many others, was upset by the war, had also suffered from a lack of international recognition, playing just one friendly for France in a 6–1 defeat against Bulgaria on 24 March 1938.

He died of a heart attack during a Marseille veterans football match at the age of 54 on 4 October 1970, twenty-eight years to the day after his memorable feat against Avignon.
