The 20-year-old is Celtic’s third new signing this summer; the transfer window closes at 11pm on Friday
Celtic have signed defender Alex Valle on a season-long loan from Barcelona.
The highly rated 20-year-old, who spent last season on loan with Levante, signed a new deal at Barca before completing his move to the Scottish champions.
He is the third new player to join Celtic this season alongside Kasper Schmeichel and Viljami Sinisalo, while Adam Idah and Paulo Bernardo both completed moves after loan spells last term.
