Celtic will have their transfer resolve tested over Matt O'Riley with Galatasaray targeting the star in a mega-money deadline day deal, according to a report.
The Danish international was subject to interest from across Europe during the January window with Atletico Madrid and La Liga title hopefuls Girona launching bids for O'Riley after a stunning season for the Scottish Premiership leaders that saw him score ten and assist 12 so far.
But Celtic are in no rush to lose him and it is understood it would likely take a club record bid to take the 23-year-old away from Glasgow's east end.
But that does not appear to have deterred Galatasaray as they looks to splash some of the £30million they received from Bayern Munich for Sacha Boey before the end of the Turkish transfer window.
