Hughes is under huge pressure with QPR bottom of the table.
Taarabt told the Rs website: "You can see that we've got the quality in the group. We have a lot of good players - but I just think we have to start games better. If you are going behind all of the time, it's very difficult.
"I know we keep saying it, but we haven't had the same starting eleven twice this season. Every game, someone gets injured.
"For the manager it's really difficult, because when he makes substitutions, it's not for tactical reasons but for injuries."
