Leeds boss Marcelo Bielsa bemoaned side’s poor defending from set-pieces after their FA Cup defeat at QPR.
Jake Bidwell headed in the winner for Rangers from Luke Freeman’s corner with 15 minutes remaining.
Keeper Bailey Peacock-Farrell had kept out two previous Bidwell headers from Freeman corners.
“We lost because we didn’t deal with some balls we should have dealt with. We didn’t find the right solution from set-pieces,” Bielsa admitted.
“We took decisions that were not useful for us and we didn’t need to take those kind of decisions.
“When you look at the dangerous situations of the opponent, they have a common factor; when we lost the ball and on set-pieces.
“Apart from this aspect – the wrong passes and the set-pieces – we would look at the game and say our opponents did not deserve to win.
“Every week we designate a high percentage of our time to set-pieces. So we will look at what we have done wrong and try to correct it. You correct these things with experience.
“The performance from the players today was good. But we made too many mistakes and if you don’t defend well then it is very hard to win games.”
