The 25-year-old is quoted by the Daily Star as saying: "It has always been my dream to play in the Champions League.
"If a club like Celtic wants me to play for them, I would be very honoured to play for them and wear that special jersey.
"The club has such a great history with some of the best football fans in the whole footballing world."
Loe has made 16 appearances for the La Liga side during this campaign.
