Marcelo Bielsa gave his reaction to seeing his side lose to Arsenal at Elland Road.
The Whites were hit by multiple injuries heading into the game to many first team regulars, but fought hard throughout the match.
Raphinha pulled a goal back for Bielsa's side to offer late hope, but the visitors ultimately had done the damage with three first half goals, before adding a late fourth.
The Leeds United head coach gave his thoughts after the full-time whistle.
He said: "It was two different halves.
“The second half, we could have won it, but in the first half we could have lost it by more goals.
“The conclusions are for myself. The losses of the ball in our own half and in the centre of the pitch increases the offensive power of the opponent.
“For us to increase the amount of danger we can create, we need to recover the ball when they play it.
“They managed to take the ball off us when we were trying to build the attack, and we couldn’t. I think that’s what explains the difference.
“We prepare ourselves with all the players, to try and prevent those thing that are not convenient for us, and to provoke the things that are convenient for us.
“They prevented us from getting into their half with combination play and through their recoveries in the build up of the play, they created danger.
“We didn’t manage to take the ball off them and that made us create less danger."
