QPR manager Ian Holloway gave his thoughts to www.qpr.co.uk, as Rangers slumped to a disappointing 1-0 defeat to rock-bottom Rotherham United in the Sky Bet Championship.
Izzy Brown scored the only goal of the game at The New York Stadium - to hand the hosts their first win in 16 matches.
Holloway told www.qpr.co.uk: "It's a horrible feeling. I hate losing games, as we all do.
"The second half didn't promise as much as the first half. And I think that's what disappointed us all - the fans included.
"The goal changed the game and then we allowed them to hang on to their lead far too easily. That's what disappointed me.
"Our shoulders dropped after the goal and that needs to change."
Holloway added: "I want to apologise to the fans who travelled here in great numbers. We didn't produce the 90 minute performance I was hoping for.
"I thought we did well in the first half. If we'd have got a goal in that first period, I'm sure we'd have got something from the game.
"The goal was poorly conceded. You can't concede like that from a throw in.
"That was very disappointing. We had three or four players who could've stopped it.
"We looked a threat in the first half though. But we don't make things easy for ourselves.
"We created chances in the first half. But the lack of chance creation in the second half was very disappointing."
Rangers host Derby County on Wednesday night before welcoming Aston Villa to Loftus Road next weekend and Holloway has challenged his players to show more belief.
"The players are very disappointed," he said.
"They need to believe in themselves a bit more and show a bit more commitment to doing the things we are practising on the training ground.
"We look like we are taking big hits when we concede.
"We've got to just get on with it and show a bit more belief."
