Mark Warburton refused to criticise defender Yoann Barbet for giving away a penalty against Swansea just minutes after his QPR side had clawed their way back into the game.
Jordan Hugill cancelled out Bersant Celina’s opener on Wednesday night, only for Barbet to trip Jordan Garrick and allow Borja Baston to restore Swansea’s lead from the spot.
Sam Surridge netted the third to rubber-stamp victory for the visitors and boss Warburton said: “You’ve seen how good he (Barbet) can be.
"You’ve seen his passing qualities and that he reads the game very well.
“I think he’s been very good. Yoann and Grant Hall have worked very hard to form a good partnership.
“But we haven’t had a clean sheet yet and that’s down to the team, not just down to Yoann or Grant.
“We get the equaliser and I think one team are going to win it. To then concede four minutes later, in a very naive manner, we have to learn from that.
"We’ve been the masters of our own downfall in certain parts.”
