The Football League's latest figures show that Walsall spent £32,590 on agents' fees in the 2009/10 season.
The figure is not far off the £29,340 they spent in the 2008/09 campaign, as 21 of 24 clubs in League One paid a service for a licensed agent.
The publication of Football League clubs' spending on agents` fees has revealed that money committed has increased in the last 12 months from £8.8million to £12.7million.
Football League chairman Greg Clarke voiced his concern, saying: "Given the current economic climate, it is worrying to see such a significant amount leaking from the game.
"This year`s figures demonstrate a considerable increase on those of last season and it is essential that clubs work to reduce this liability over the coming campaign."
