Manchester City boss Pep Guardiola faces a selection headache as he will need to leave out one of the club's January signing from the Champions League knockout stages ahead of Thursday's deadline.
City, amid a prolonged run of poor form, spent €210 million ($219m) last month on forward Omar Marmoush, midfielder Nico González and defenders Abdukodir Khusanov and Vitor Reis.
Clubs must inform UEFA of their 25-man squad for the knockout stages by 11 p.m. GMT on Thursday (6 p.m. E.T.), however each club can only make three changes from their league phase squad.
