"We were lucky, because we scored in a very difficult moment of the match," he said.
"Maybe we deserved to win in the second half. In that match we defended really very well, because they only had three goal opportunities, no more, and it's not easy to give them only three or four opportunities. At home they have scored 43 goals in 13 matches, more than three on average, so we need to defend very well.
"We need to be very fast when we recover the ball, because if you are first to the lost ball they are able to press very well, and it's very difficult to exit the situation.
"If we are able to do that, we can find spaces, but it will be very difficult."
