The Baggies remained just outside the top four with a 2-1 victory at Loftus Road courtesy of an own-goal from R’s keeper Rob Green which came before Djibril Cisse got one back for the home side following Chris Brunt’s opener.
"Marc didn't do a lot wrong, he stood his ground and Rob didn't get around him, made a mistake and it was a goal to us,” he told Sky Sports.
"I don't think that should deflect away from the gulf there was between the two teams at stages during the game. The first half was quite even, we got our noses in front, but we looked like the team playing with confidence and QPR are the team that is struggling. We passed the ball well and had some half chances.
"We played good stuff and the start of the second half I thought we were tremendous, we opened the game up and QPR had to come at us. We made a number of chances to make the game 2-0, 3-0, 4-0 and it could have been over before QPR got the goal which made it a little bit more nervous for us towards the end.
"When you are down the bottom, you are going to shout for every decision. Every manager is entitled to shout for it but I think you can't give it, it's impossible for the referee to give that.
"I don't want to talk about controversial decisions, I want to talk about how good my team is and how well we have done at the halfway stage of the season."
