The Dutchman parted company with the Cottagers one day after the club's 3-0 defeat to West Ham United at Upton Park on Saturday - their fifth straight defeat in the Premier League.
However, the 24-year-old - whom Jol signed on loan from QPR earlier in the season - says that his teammates are equally culpable for the club's run of form as the recently departed manager.
Speaking to The Fulham Chronicle, Taarabt said: "What went wrong? I don't know. The manager was a great guy; always positive but at the moment it is not happening.
"If you don't win four or five or five games, the manager gets the blame - but I think the players should have this blame too.
"If we're not doing what we should on the pitch, then the players should be asked the same questions as he was asked."
Rene Meulensteen, who worked at Manchester United under Sir Alex Ferguson, has since been appointed as manager at the West London outfit after initially joining the club as head coach.
Fulham, who sit 18th in the Premier League table, three points adrift of Cardiff City, host Tottenham at Craven Cottage on Wednesday.
