Red Star Belgrade have admitted their giant striker Nikola Zigic has been the subject of an offer from West Ham but insisted he will not leave the club until the summer.The 6ft 8in target man, who will feature in Serbia & Montenegro's World Cup squad, has been linked with several clubs with Germany's Hamburg also interested in signing him. Red Star director of sport Stevan Stojanovic, the goalkeeper in the Belgrade team that won the 1991 European Cup, confirmed an offer had been received from the east London club. 'Yesterday (Thursday) we returned from Paris, where we held a meeting with some of the clubs interested in Zigic. West Ham is one of them,' said Stojanovic. 'But, we postponed all talks until the summer as we need our main striker for domestic competitions,' said Stojanovic. Zigic has just been voted Serbia & Montenegro's player of the year for the second time in three years. The 24-year-old, who has scored eight goals in the First Federal League and six in the UEFA Cup this season as well as three in World Cup qualifiers, said: 'It's true that I was in Paris because of transfer talks. 'But, even if the talks were quite open, I'll stay in Red Star until June. That's the wish of my club and my wish too although I'm flattered that West Ham wanted me, just like some other clubs from England too.'
