Ahead of Manchester United's visit to the King Power stadium on Saturday, Louis van Gaal has leapt to the defence of this season's Premier League surprise package.
When asked about Leicester's chances of winning the title, the Dutchman made a startling response: "It is possible, I think."
Vardy knows all about Man Utd
Jamie Vardy, the league's top goalscorer with 13 goals and ten in as many games, certainly has what it takes to thwart the seemingly rock solid defence of United.

Last time the Red Devils visited the King Power stadium, they faced a determined, excited but unproven winger. Vardy was making his first start in the Premier League as he almost single-handedly demolished Van Gaal's side as Leicester overcame a two goal deficit to shock the country by racing to a 5-3 win.
When discussing their last visit, the United boss also commented on Vardy's performance: "He was already a very nasty player for us last year," he claimed.
"He scores, he provoked a penalty, now scoring 10 goals in a row, he is a great player. I only know Dennis Bergkamp as a player who did the same with Ajax. It's not so easy to do that."
Will Leicester's surge of form last?
Most Premier League campaigns have the same old story of an unexpected success.
A team that nobody expected to perform, rises higher than ever before. But the outcome is always the same, in the end, they wear themselves into the ground. But, Van Gaal agrees with Arsene Wenger's comments earlier in the week and thinks Leicester can extend their good form.
"Normally these kind of clubs can compete for long time, then at the end it becomes more difficult," he said.
"But in England because of the quality of the teams, because every team has the money to buy players - and they have bought players - the difference in the Premier League between the clubs is not so high."
With difficult fixtures against United, Chelsea, Everton, Liverpool and Manchester City approaching in the near future, we are close to judging whether the prospect of a Leicester City title challenge is realistic or not.
Van Gaal's struggles
Life for the United manager has been tough of late, despite picking up point after point in the Premier League, he has been under heavy criticism for his 'boring' style of football by several high profile figures.
Ranieri has faced Van Gaal seven times in his managerial career - losing four and winning three - and he was prepared to give his backing to the Dutchman:
"He is a fantastic manager. The respect is very big. Under him United are slowly, slowly getting better, he is building.
"From last season to this season, now the defence line is fantastic and it is difficult to break their lines. When you play against great teams, you have to see how your team reacts. For us this is another match to know where we have to improve."
It is clear to see the two managers have respect for each other, but after an amazing period of success for the Foxes, will United show them the respect required to overcome one of their biggest tests of the season, or will they fall short against resurgent Leicester side, rampant for success?
