West Bromwich Albion boss Steve Clarke is convinced of the class of QPR's signings.
Clarke backs the suggestion QPR's new players are taking time to bed in - and that is cranking up the pressure on Hughes.
He said: "Sometimes it gels quickly, other times it takes a little bit longer. That's the case with QPR. They've got some really good players but it hasn't quite clicked.
"It's up to us to make sure it doesn't and they're still struggling going into the international break."
