WATCH | 'We're waiting for you', Real Madrid's Luka Modric tells Neymar

Real Madrid midfielder Luka Modric urged Neymar to join him at the Uefa Champions League winners after swapping shirts with the forward following Sunday's international friendly between Brazil and Croatia.

Paris St Germain's Neymar shone on his first appearance after a lengthy injury layoff by breaking the deadlock in his side's 2-0 win over Croatia at Anfield, skipping past two defenders before smashing in off the underside of the bar.

Neymar, who joined PSG in a record $259-million move from Real's arch-rivals Barcelona, was filmed exchanging and signing shirts with Modric after the game and the video was broadcast on Twitter by the Brazilian soccer federation.

Amid growing speculation the PSG forward will walk out on the Ligue 1 champions for Real, Modric can be seen saying to Neymar "We're waiting for you", prompting Neymar to laugh and smile.

Spanish newspaper Marca reported last month that the player’s father and agent, Neymar Sr., had told PSG his son wanted to leave immediately, saying he met Real directors in Paris in December.

Real president Florentino Perez has admitted his side tried to sign Neymar before he joined Barca in 2013 and has reiterated his desire to bring the Brazilian to the Spanish capital.

Neymar scored 28 goals and provided 16 assists in 30 appearances in all competitions in his first season for PSG before sustaining an ankle and foot injury on February 25.
