Under-fire head coach Chris Ramsey said he accepted the criticism from frustrated QPR fans following the 0-0 draw at home to Sheffield Wednesday.Ramsey, whose team have won only one of their last seven matches, was barracked by fans who chanted ``You don't know what you're doing'' when he replaced lone striker Jay Emmanuel-Thomas with Leroy Fer with 21 minutes remaining.``It doesn't help me, but at the end of the day that's part of being sa t in this chair,'' Ramsey said.``Unfortunately, in this game one week you know what you're doing and the next week you don't.``The fans are entitled to their opinion. They've come here on a Tuesday night and are disappointed not to get the three points.``I can assure them we are trying our best to make them happy. Sometimes we will fall short of the mark.''Emmanuel-Thomas was recently recalled to the QPR side to replace top scorer Charlie Austin, who is currently out with a hamstring problem.``Jay is obviously getting back into it and he lasted as long as I thought he would,'' Ramsey added.``We brought on a Dutch international; not a youngster but a proven player``No player wants to be taken off. But Jay did well when he was on, he played his part and Leroy did well when he came on as well.``I'm obviously disappointed we didn't get the win. But I am pleased with the clean sheet as we haven't had many of those this season.''Meanwhile, Sheffield Wednesday boss Carlos Carvalhal refused to comment on a first-half incident which led to Owls winger Modou Sougou carried off shortly before half-time.Wednesday's players felt Rangers defender Clint Hill should have been sent off for a challenge which left Sougou, who would have been through on goal, pole-axed.Carvalhal, whose team face Rotherham in a South Yorkshire derby on Friday, said: ``Sougou has been taken to hospital with a suspected dislocated shoulder.``I won't talk about the referee. Referees have a difficult job to do.``Everyone can see it, so they can make their own judgement on these things. There are people who are there to analyse these things and that is what they will do - it's their job to analyse it.``I'm disappointed to have taken only two points from the last two matches. I wanted six, so I'm not really satisfied.``I made seven changes to the team, though, and in that sense it's a good point. We'll be ready for the derby.'' ends
