Jol's strugglers were well beaten at Upton Park, but the Dutchman thought that his side were "unfortunate" in the game.
"We were unfortunate because of the timing of the goals really," Jol told Sky Sports News.
"The first goal killed us, it was 46 minutes and the other two were 82 and 88 so that sums it up really. We wanted Kieran Richardson to come off but we couldn't [make the change] and he couldn't sprint 100% up the line for the goal.
"Moussa Dembele also pulled his hamstring for the first time in his career after 30 seconds, so that sums it up really."
The defeat leaves Fulham in the relegation zone in the Premier League.
