Rio in WC vow

Rio Ferdinand is adamant that he will be fit to play in the 2010 World Cup in South Africa. The Manchester United defender has suffered a series of niggling back and calf problems this season and has not played since late October when he was well below par. "I'm confident I'll be fit. There's no question I'll be ready for next summer,” vowed Ferdinand on Thursday. "It's the worst thing for a player to be injured and to be just watching your team, so I've been working hard in the gym to get fit. The treatment on my injury is going well. I can see the light at the end of the tunnel. " The former West Ham and Leeds star has played only 12 of the 21 internationals since Fabio Capello took over as England boss two years ago.
