West Ham United co-chairman David Sullivan calls agents 'scavengers' after 'deeply unpleasant' transfer window West Ham, who are £100 million in debt, made four signings in the January window - Joe Cole, Marouane Chamakh, Emanuel Pogatetz and Wellington Paulista - while Sullivan took "hundreds of calls" during a frenetic January. Sullivan, who took over at Upton Park in January 2011, told the Daily Mail: "There are a few agents who are very good at what they do (and are millionaires as a result of that), but others who want to force their way in. And do whatever it takes. Some of these people are like scavengers. It was all deeply unpleasant and I'm glad it's over. Sullivan did reserve some anger towards the growth of player power after condemning Peter Odemwingie, the West Bromwich Albion striker. Odemwingie was left high and dry on Thursday night after driving to Loftus Road, apparently believing that a deal for him to join Queens Park Rangers had been agreed. "You cannot give in to players like this," Sullivan said. It is the same as giving in to terrorists or kidnappers. If you pay the ransom, they will only come back for more. Sullivan seems to have a habit of giving frank interviews in February. This time last year, Sullivan gave an in-depth insight in to the workings of West Ham, from trying to sign Fernando Torres on loan and how he dealt with Sam Allardyce.
