The Foxes failed to build upon their impressive start to the season, with Gabriel Obertan’s 71st minute strike enough to gift Newcastle their first three points of the season.
The introduction of an attacking threat gave Leicester domination of the game, but they could not take advantage of their control, and they fell to just two points above the Magpies who reside in the final Premier League relegation place.
Speaking to the official Leicester website after the game, head coach Nigel Pearson spoke of his disappointment at the result.
He said: “It’s disappointing – I think we had the chances to get something out of the game and the sucker punch was conceding a goal on the counter attack.
“It was a disappointing outcome for us but it’s something we’ll have to deal with.
“We felt at times we could have played with a bit more intensity in the first half but that happens from time to time.
“We managed the game relatively well in the first half, limited the chances they had and put them under a bit of pressure.”
Despite putting in an impressive performance, Pearson revealed the reason that the Foxes failed to capitalise and claim the victory - with a lack of quality in the final third costing the Championship winners three points.
“Ultimately, when our attacking situations arose we weren’t able to do quite enough with them.
“I’m not one for spending too much time playing the luck card. During games you get opportunities to score but also we need to defend in the right way as well.
“We had some very promising situations but what we didn’t do is find enough quality to take advantage.
“For instance, we got into their box on a number of occasions late in the game and didn’t produce enough clear quality to create chances – we need to get better at it.”
Newcastle will be looking to build upon their first win of the season next week, as they travel to North London to face Tottenham Hotspur on October 26.
