They are now allowed to train in groups of no more than ten with the next phase being a return to full training before a possible La Liga restart behind closed doors on June 12.
Though six-time Ballon d’Or winner Messi was filmed training on his own, and it seems the Argentine doesn’t need his team-mates to help him practise his heading.

Setting up with an elevated net around eight yards away from himself, Messi is seen doing some kick-ups.
He then uses his left foot to kick the ball high in the air before superbly heading it straight into the basketball-style net.
La Liga are keen to return and finish the season with Messi’s Barca top of the table by two points, ahead of rivals Real Madrid.
Messi had recently admitted that returning to football behind closed doors will be a strange sensation.
Messi said: “This break may end up benefiting us, but we are going to see if they can start the competitions and there we will get out of doubts, because we will check the level we have or can reach when we start.
“The risk of contagion is everywhere, when you leave the house the risk is already there, therefore I think that you do not have to think about it much.
