"We gave in the first part of the season some really, really good games and performances. But the moment we felt mistakes, especially in defence - an own-goal at White Hart Lane, our miss at Celtic in Glasgow - we lost a little of our confidence to play," the Spaniard said about his team's football.
"And at times my ideas were not good, because I'm still getting to know the players, to know what is the best position, the best way to play, to adapt to them.
"Sometimes I have an idea: three at the back or play a player in a certain way, and sometimes it didn't work. And, when that happens, I never complain to the players. Because I see them training, how they suffer, and what they did in the last game against Burnley after 65, 70 minutes with 10 against 11, two days after Anfield," he said in a press conference.
You have to look at yourself and see what you have to do to help them find each other and play to each other more fluently, not all the time with an aggressiveness. That is my job. I have to help them and I tell them that. And most of the times we were not good, it was my responsibility."
