Luiz told BT Sport: "We did a great first half, it was maturity in the second half. We have to be honest and humble to admit physically we are not ready.
"But where physically you are not there you have to put your hearts in.
"You can't change from zero to 10 in one day, one week, one month - but it is beautiful to see how these kids start to understand their commitment, their behaviours of what they need to do for big things in life and big things in football.

"In life when you are happy, the results can be totally different. If you sleep happy, you can sleep four hours and better than sleep sad for eight hours.
"If you work with happiness and believe in what you are doing it is totally different.
"Our season isn't there. We started very badly, but things can change and there are still some titles to fight for and some improvements for the future."
