A move abroad for Barcelona midfielder Alex Collado could be on.
Collado is set to leave on-loan this month, with local rivals Girona.
However, Relevo reports that Olympiacos and Celtic are also on the table. The player, who spent last season at Granada, must decide what is best for his future- whether to go abroad to play or stay on in La Liga.
Barça are interested in him continuing his training and accumulating experience abroad.
The plan is to monitor him and help realise his growth in a new loan exit.
