It comes as the Argentine World Cup winner is linked with a possible move to La Liga giants Real Madrid.
In a recent interview, he said he would “like to live in Spain” and that Madrid reminded him of Buenos Aires.

Spanish defender Marc Cucurella was also summoned after criticising the club’s transfer policy.
However, the left-back is available to play against Port Vale in the FA Cup tomorrow.
