The Cottagers' manager wants his team to dip into the transfer market ahead of the new season following the departures of several key men
The loan signing of Sascha Riether from German outfit Koln and free agents Hugo Rodallega and Mladen Petric have meant the Cottagers have not spent any money on transfer fees during this transfer window.
"If everything stays as it is I am pretty satisfied, and we are still working to get two or three players in," Jol told Sky Sports News.
"It depends on what happens. You've heard all the rumours about the big players, our good players, so hopefully they will stay. We want them to stay, that is important."
"Then Dickson [Etuhu], he wanted to play games and was asking me for the last couple of months, so we had to let him go as well.

"We need at least a midfield player, in the midfield area."
After losing four strikers since January, Jol suggested his side are lightweight in that area and will need to bolster their forward line.
"Up front, we lost four strikers - Orlando Sa went, Bobby Zamora, the Pog [Pavel Pogrebnyak], Andy Johnson went," he added.
"We have got two, Rodallega and Petric, so at least we need one or two strikers as well."
