Fulham boss Jol happy to uncover rough diamonds in market
The winger has been ruled out for the season due to injury.
"I'd like to play well-known famous players but it's not always possible. There are other clubs scouting the stars so we have to come up with a different idea," Jol said.
"There are a lot of other players in football that you have to take when they are not doing well if you want to get them cheap - but they did quite well for us here.
"So we were happy with Dejagah. He was cheap but he played for a good club, they were champions in Germany and I knew him from that."
