Craig Bellamy and Scott Parker have both been linked with moves to Manchester City while Matthew Upson and Lucas Neill are also reported targets.

West Ham have been fielding regular enquiries and although chief executive Scott Duxbury admitted this week that every player has his price manager Gianfranco Zola is not under any pressure to sell.

After watching the Hammers book their place in the FA Cup fourth round with a 3-0 win over Barnsley, Clarke said: "I would hope and expect them to still be here this time next week.

"The January transfer window is there and you have to put up with it. There's going to be a lot of speculation about players coming and going. We come in every day and try and do what we can.

"Gianfranco is in close contact with Scott Duxbury and technical director Gianluca Nani and so we have an opinion on transfers.

"But the performance showed how committed the players are. We can talk about speculation in the transfer window all day but it's only speculation."

Zola has no money available for new players but the return to action of England international Kieron Dyer 17 months after suffering a broken leg is like a new signing for the Hammers.

Dyer, who underwent three operations, came off the bench for the last 20 minutes to make only his fourth appearance since signing for the Hammers in the summer of 2007.

"It was good to have him back because he's had a dreadful time with injury," Clarke added.

"We all feel for him and he's been working ever so hard just to get back on the pitch again.

"He showed some good touches but he's also not near full match fitness but we can work on that and he really could be like a new signing."

Barnsley reached the FA Cup semi-final last season after memorable victories over Liverpool and Chelsea but their hopes of another Wembley appearance were dashed as the Hammers cruised to victory with goals from Herita Ilunga, a Mark Noble penalty and Carlton Cole's header.

Barnsley manager Simon Davey said: "We gifted them two goals in the first half and it's not like they've had to cut us open to score.

"The penalty was probably a turning point and it changed my whole half-time team talk.

"We created chances but we didn't break down their defence. To concede just before the break was crucial and it became an uphill task, and the third goal was a killer."
