Paris Saint-Germain are reportedly keen to pay the Brazil striker's €222million buyout clause, with reports in Neymar's homeland suggesting he is receptive about a move to Ligue 1, where he would be the league and team's biggest star.
Gerard Pique attempted to add a definitive air to the rumour's end, by posting "He's staying" along with a picture of Neymar on social media on Sunday.
However, Casemiro may well have added more fuel to the fire, by suggesting that his international colleague could find a home at the Santiago Bernabeu.
