Asked if he has the confidence of Fulham owner Shahid Khan, the billionaire owner of the Jacksonville Jaguars NFL franchise, Jol pointed to the key difference with American sport.
Jol said: "For the owner it's different. In America you can't go down. (If) the Jaguars are bottom of the table, they can't go down.
"In England you can go down, so that makes people nervous. I can appreciate that."
Asked if he is now nervous about his own position, Jol said: "I know that we can do a lot better.
"I've got players who have played 300 games. We had all the size in the world today and we still lost headers in the far post, even when we are 6ft 6ins or 7ins. And that is worrying."
