CSKA Moscow will have to do without striker Tomas Necid for "several months" after the Czech international was told he needed another operation on a ruptured knee ligament, his agent said today. The 22-year-old sustained the injury in a Russian league match in June 2011 and underwent a first operation in Barcelona last July, making his comeback in January. But Necid's agent Jiri Muller was quoted by the CTK news agency as saying that the ligament had "not healed well" and the striker who has scored seven goals in 26 matches for the Czech Republic would have to go under the knife anew.
