Lionel Messi is out of contract with Paris Saint-Germain at the end of the campaign and there has been speculation that he will re-join Barcelona next summer – but what shirt number could he take?
Messi exited the Camp Nou 12 months ago as he joined PSG on a two-year contract after the Catalan club were unable to afford his new deal. Barca's economic vice president Eduard Romeu recently suggested that a sensational return to the club for the Argentine would be possible next summer.
Those comments were echoed by Barcelona club president Joan Laporta, who added: "We have a moral debt with him in this sense. We would like the end of his career to be with the Barca shirt and being applauded in all fields."
