What does it take to beat Newcastle?
Leicester manager Brendan Rodgers didn't have the answer.
Brendan Rodgers said: "It's difficult to break down a team like that. It's an area we will get better at. There wasn't a lot in the game, our final pass just wasn't there but we gave everything. We couldn't break down their defence.
"We will learn from it; this is why I am here. In games like that, you have to stay patient and have tactical discipline. The players have been first class since I came here but if you're not quite on it, a result like this can happen.
"The speed of our passing in particular can be much better. We let them get into shape too early. It needs to come quicker. We changed it around a few times but it was one of those evenings. It will be good for our learning going forward."
Newcastle manager Rafa Benitez said: "It was a good game against a good team. We did very well. Our players worked so hard. This relationship between the players and fans means a lot to us. The players and fans tried to do their best.
"As a coach, you always have a game plan. You can prepare however you want but it depends on the players to make the difference.
"The problem against James Maddison or Jamie Vardy is you have to concentrate from the first minute to the last. We are really pleased with the clean sheet and three points. You have to enjoy today and be ready for the next one.
"We had two or three counter-attacks that we could have had a little more composure and scored more."
