Meanwhile Celtic have slapped a not for sale sign on Reo Hatate after reportedly booting out a £10m offer for the Japanese playmaker. An unnamed club from France are said to have tested Celtic's resolve but the fans' favourite won't be allowed to leave during this window.

An unnamed French club offered £10million for Reo Hatate this week, but Celtic rejected the offer. The Daily Mail reported that Celtic did not want to lose two key players in the same window after already selling Matt O'Riley to Brighton for a record-breaking £30million.
