Mark Hughes, the Fulham manager, has been impressed with the ability of forward Bobby Zamora since taking over at Craven Cottage. Zamora, 29, has scored three times for the Cottagers this season, and made his England debut in last month's friendly win over Hungary at Wembley. He was ruled out of the squad to face Bulgaria and Switzerland because of a thigh injury. Hughes took over at Fulham this summer, replacing Liverpool-bound Roy Hodgson, and was surprised at how good Zamora is. "When you come into a new situation you are not quite sure what you are getting, but Bobby is a top class Premier League striker," he told Fulham's official website. "His link-up play has impressed me and is better than people give him credit for. Bobby is quite a package and a threat. His link-up play and team work is excellent and he is a big factor in why we have started so brightly. "He is very confident in his game and he is enjoying his work. At the moment he is able to transfer the work on the training ground on to the field of play and is playing really, really well." Fulham are believed to be preparing to offer Zamora an improved contract to ward of possible suitors. Liverpool raised the possibility of signing him when negotiating for left-back Paul Konchesky - who did move to Anfield - but were told he is not for sale. Fulham rebuffed three formal bids during the transfer window.
