The Dutch boss has confirmed that talks are ongoing between the London club and the experienced center back and believes that the Cottagers have made a strong enough offer.
The 31-year-old has yet to commit his future to the West London side, with his current deal set to expire next summer, but the Dutch boss is confident of securing the experienced defender's signature. Jol said that the club has already offered the Texas-born Norwegian a new deal that he hoped could lead to a conclusion in talks before Christmas.
"We are talking to [Hangeland]," Jol told the Fulham and Hammersmith Chronicle. "He knows what we've offered him is good, so hopefully he will make a decision in the next month or so. We're optimistic."
Fulham currently sits in ninth place in the Premier League with 16 points from 13 games, but lost 1-0 to Stoke City on Saturday afternoon.
Hangeland missed the match at the Britannia Stadium due to the three-match suspension he received for a straight red card during the Cottagers' 3-1 home defeat to Sunderland last weekend, and he will be out until the game against Newcastle on Dec. 10.
