Sociedad set to rescue Mladenovic Rangers are set to loan out-of-favour midfielder Dragan Mladenovic to Real Sociedad, despite the closure of the January transfer window. Sociedad have been given special permission by the Spanish FA to sign a player due to an injury crisis. Mladenovic will effectively replace former Rangers midfielder Mikel Arteta, who has been loaned to Everton. Sociedad say they will pay Rangers £150,000, with an option to buy the Serbia & Montenegro international. Mladenovic's loan move is subject to him passing a medical. The 28-year-old, who joined Rangers from Red Star Belgrade for £1.2m in the close season, is expected in San Sebastian later this week following his national side's game against Bulgaria. Sociedad are in 15th place in the 20-strong Primera Liga, just two points above the relegation zone. Special permission from the Spanish FA came after an injury to central defender Igor Jauregi. The versatile Mladenovic can also play in the back four. His agent said last month that Rangers had told him to find the player a new club. Mladenovic's time at Ibrox has been plagued with injury and he has made just six starts in six months with the Glasgow club.
