Celtic midfielder Reo Hatate has informed the club that he wants to leave this summer, according to reports. The 28-year-old Japan international remains under contract until 2028 but has fallen out of favour under Martin O'Neill. Meanwhile, Ross Stewart's contract situation at Southampton remains uncertain due to a contract loophole. The Scotland striker missed the expiry date on a contract extension clause due to the 'Spygate' scandal that denied them promotion to the Premier League. Celtic have also been linked with a move for 17-year-old striker Michael Noonan, who is in advanced talks to join Ajax from Shamrock Rovers. Additionally, Youssef Chermiti is one of the names on Galatasaray's list of possible signings, but Rangers will demand £25m for the 22-year-old striker.
