Former Real Madrid star Kaka feels that if Neymar wants to join the Spanish giants he "must do it", while sympathising with Brazil's talisman amid the pressure he is under at the World Cup.
Speculation over a possible move to Madrid has been rife since Neymar reportedly met Paris Saint-Germain president Nasser Al-Khelaifi to express his unhappiness in the French capital after just one season with the Ligue 1 champions.
Kaka, who played for Madrid between 2009 and 2013, suggested a move from Parc des Princes a year after arriving from Barcelona in a world-record €222 million (£196m/$259m) move might arouse suspicion over Neymar's motives for moving to France.
