"We are very disappointed. We didn't play a good match, we were bad," said the midfielder.
"I don't know how to explain. We didn't play well from the start when we weren't using the ball well.
"We gave the ball away too much and despite their problems they had, they ended up giving us problems. I had some difficult moments but now we have to work, get our heads right. It is not a crisis, it is one of those matches that happen. You get games like that.
"We have to work at training. We are not worried. We have to lift our heads up, start again and look forward."
