QPR have won five of their last six games and are currently top of the Championship table, but Redknapp said after the game that today's performance was the first time this season that the Hoops have played to the best of their abilities.
"I've walked away from games this season thinking we could have played better, but I thought we were first class from start to finish today," the 66-year-old told the club's official website.
"That's the best we've played all season. We passed the ball well, we kept possession of the football for long periods and looked a classy side today.
"Everyone wanted the football, everyone wanted to play their part and I thought we were excellent, each and every one of them."
QPR are the Championship's form team, having won five of their last six matches.
