Neymar's father insists his son has no chance of playing in Paris Saint-Germain's Champions League showdown against Real Madrid and believes surgery on a broken foot is the "quickest way to accelerate the player's recovery".

The world's most expensive player sustained a hairline fracture to the fifth metatarsal of his right foot during PSG's 3-0 win over Marseille on Sunday.

PSG head coach Unai Emery told reporters on Tuesday that there was "a small chance" Neymar could face Real Madrid in the Champions League on March 6, when the Ligue 1 leaders will aim to overturn a 3-1 first-leg deficit at the Parc des Princes.

Emery explained a decision was yet to be made on whether Neymar would undergo surgery but, with fears growing in his homeland over the forward's fitness for Brazil's World Cup campaign, Neymar Sr told ESPN Brasil that route will bring about a quicker return to action and dismissed the notion of his son featuring in any potential comeback versus Madrid.
