English player Jack Butland, 32, is a standout performer in the Champions League qualification rounds but struggled to hold a starting spot last season. Richard Foster warned Rangers against selling him, as it would be devastating to lose their goalkeeper. Butland has interest from other clubs due to his specialized position, and Rangers would need a decent amount of money to replace him. His current contract runs until 2027, and his value is estimated by Transfermarkt to be €1.50m.
