Real Madrid boss
Gabriel Pires and Luciano da Rocha Neves scored within four minutes of each other to drag the hosts back into the tie after less than impressive defending from captain Sergio Ramos on both occasions.
"At the time I got angry, I was furious", the Frenchman told the club's official website. "We let the opposition back into the game and that's football because you never know what can happen.
"In two minutes we made things difficult for ourselves."
However following the collapse, the 44-year-old was impressed with how his side rallied together to secure the win.
"It's to be expected that he gets angry because they all went to play a full game", the former France international said.
"I bring him off a lot, but that's because he's an attacking player and he works very hard. That happens at lot to the players who play up top, like Karim.
"It's normal for him to get angry because I brought him off, but there's nothing more to it. I try to do what’s good for the team. He’s important to me, to the team and to everyone."
The win saw Madrid reclaim top stop by two points still with a game in hand after being temporarily dethroned by Barcelona following their 3-0 win earlier in the evening.
