"It's actually quite simple," he said. "We concede only three chances over the course of the whole game, three from set-plays.
"Their goal, first of all, the free-kick. You have to be more controlled, it's not necessary to make a foul there. Then the ball is coming into the box and it's not good defending.
"And we had poor decisions in the final third. We came so often in good positions, behind or in front of their backline, we had three players there in that moment. We didn't have an impact to get to their goal and so whatever, the extra pass, final pass or a shot.
"The quality was just not good enough in that part of the game. In the final part of the game, we didn't play our best game."
