The season isn't nearly over yet, but there are already a number of transfer rumours surrounding Celtic and possible summer moves.
The Scotsman have reported that there is interest from the Bhoys in Dundee goalkeeper Scott Bain, whilst Goal recently suggested that that Ronny Deila had his eye on Groningen centre back William Troost-Ekong.
Yet the biggest rumour so far is that Celtic will look to make a move to sign Real Madrid teenager Martin Odegaard, who played under Deila at Stromsgodset in Norway.
The 16-year-old playmaker may be available for loan next season, and Deila admitted that he'd be interested in reuniting with the teenager if possible.
However, if Celtic open negotiations with Real Madrid over Odegaard, then they should at least enquire about another of their prospects, Jack Harper.
Harper, 19, is currently flying the flag for Scotland at the Bernabeu, becoming one of only a handful of Scots to play over in Spain.
Currently playing in in the Real Madrid Under-19's, Harper is considered to be one of the brightest up-and-coming Scottish players right now, along with Sporting Lisbon's Ryan Gauld.
Harper should be in the B team - Real Madrid Castilla - plans next season under Zinedine Zidane, but the chance to move to Celtic on a season-long loan alongside Odegaard could be beneficial to all.
Celtic may need a striker given that John Guidetti will not only return to Manchester City at the end of his loan, but will also become a free agent, and he'd give Deila something of an unknown quantity for defences to deal with when called upon.
Harper wouldn't need to be the main man in the Celtic attack and would instead be able to develop back in his native Scotland - so if Celtic make the call about Odegaard, they should consider Harper too.
