All eyes are waiting to see the new Champions in Premier league 2015-16. Ranieri is having more cautious and pressure, after this crucial match.
“When you change a manager, players want to show their attitude, and plus, the Newcastle players are very good, I am sure at the end they will be safe [from relegation].
“For this reason, I was waiting for a difficult match and it wasn’t one of our best performances but we showed our fantastic spirit.
“In the first half, we conceded too many dangerous actions and in the second half, we were a little more concentrated and won the first and second balls. In the first half, we lost so many balls.

He added: “It was important somebody scored the goal and then we defended very well. In this moment, it is important for us to play and to fight.”
“It wasn’t a nervous second half, it was maybe much better in the second half because the team was so close and so compact,” he added. “In the first half, they came too many times through the middle and had some good actions.
“Not always did we play well. We played well for example against Aston Villa and West Bromwich but we drew those matches 1-1 and 2-2.
“Now we play not so good as those games but we won. That is important – three points. There are eight matches to go and we continue. Our fans are dreaming and are proud of us. That’s important for us and we’ll carry on.”
“I feel I am very concentrated on the next match against Crystal Palace, and it will be another tough match,” he continued.
“Our concentration is important, we are so strong and we think about only one match. Step by step, that is our philosophy.”
