Jay Bothroyd has praised Manchester City as the best side newly-promoted QPR have faced this season.
Neil Warnock's side tackled the league leaders on Saturday and were unlucky to finish on the wrong end of a five-goal thriller at Loftus Road.
While Bothroyd accepts Roberto Mancini's squad have the best ability, he was also impressed by their worth ethic and desire to work for each other.
"They are definitely the best side," he said. "They have the best players. But it is more than just ability.
"They have an abundance of that but names alone don't make a great team. It is the work ethic as well.
"They have a world-class bench. God knows how many millions that cost, and they are improving.
"They have been in top form all season. They hammered Manchester United, are scoring goals pretty freely and generally, they keep it tight at the back."
