After an encouraging start to the season, the Cottagers have won only one of their last six Premier League games and have slipped to 13th in the table.
Jol is now scouring the transfer market for targets, and he has been linked with moves for the likes of Tom Huddlestone, St Etienne's Banel Nicolita and Jores Okore of Nordsjlland.
"We had a very good start to the season. We had a settled team before but I think we are a bit unsettled now," Jol said. "We are the only team in the Premier League who have not found their feet in general.
"If you look at Wigan, they have a settled team. They bought two or three players in the first week of January and we haven't got that.
"We don't have a lot of money to spend."
