The Cottagers boss was frustrated with his side's complacent approach in their 1-0 defeat to the Toffees at Goodison Park on Saturday, and believes it was an opportunity missed
The west London club went down to a first-half goal from Steven Pienaar and struggled to impose themselves on the match throughout.
Jol told the Fulham Chronicle:“I feel this was one of these days. We could have had a result.
“The only thing is you need to play with a bit more purpose. The first half was a bit too relaxed for me, like a summer night game.
“The second half we did a bit better in possession, but it's still disappointing.
“The players are professional. They want to get as high in the league as possible, like I do. I will give anything to be in the top 10.
“It's disappointing that we couldn't get a result in the last three or four games.”
