FC Sion President Christian Constantin has started another dispute with FIFA by seeking “several million euros” compensation after Serbia forward Dragan Mrdja was injured on international duty. Constantin tells Swiss daily Le Nouvelliste he will write to FIFA and Serbian officials demanding damages. Mrdja tore knee ligaments in Serbia's 2-0 loss in Mexico Saturday and is likely to be out for several months. The Sion president objects to clubs being obliged to give national teams their players, who then return injured. Sion is a member of the European Club Association, which wants FIFA to insure international players' salaries. Constantin and Sion are currently fighting FIFA, UEFA and Swiss authorities over a transfer ban. Clemence in hospital Former England goalkeeper Ray Clemence was admitted to hospital Monday, the English Football Association have confirmed. Clemence, who now works as England's goalkeeping coach, began to feel unwell Friday when he missed training and he was absent for Saturday's 1-0 friendly win over world champions Spain. “Ray Clemence has been unwell while with England and is having tests in hospital,” an FA statement said. Clemence, 63, was also missing when England trained Monday ahead of Tuesday's friendly with Sweden. “At this time Ray would like to thank everyone for the kind messages he's received and the FA would like to request privacy for his family,” the statement added. During his illustrious 23-year career, Clemence won three European Cups with Liverpool and also helped the Anfield club lift the old First Division title five times before moving to top-flight rival Tottenham Hotspur.
