Manchester United legend Roy Keane has blasted Leicester City after their thrashing by Champions League opponents Porto.

Leicester boss Claudio Ranieri picked a second string team for the trip to Portugal as his side's spot in the last-16 of the competition was already secure, but Keane was unforgiving in his analysis of their woeful form as they are currently sitting just two points above the relegation trap door in the Premier League.

“The warning signs have been there for the last few months with their league form and to me, the basic fact is they have lost their hunger," Keane told ITV Sport.

“Over the last few months, we see a few of their players getting rewarded with new contracts. The financial rewards are fantastic, but it can destroy a club. Too much money too soon and they players take their eyes off the ball and they are in big trouble.

“They have had a bit of success and it is hard to be critical of them, but you look at their manager, and he seems to be a very placid man, and he must be so frustrated. He must be scratching his head, him and his staff.

“I think his players are trying. It's not like they have downed tools or anything like that, but their real desire not to get beaten has all gone out the window.

“Football is all about good habits and they have lost all track of what they should be about. Their DNA last year, their work rate, its gone.

“It's been happening the last few months and they have Man City at the weekend, they are in a relegation fight now."
