The arguments against Leicester being genuine title contenders are weakening.
Their thumping 3-1 win at Manchester City on Saturday moved them five points clear at the top of the Premier League table, with just 13 games to play. Sky Bet - who had the Foxes as 5000/1 to win the league before the season - have made them 7/4 favourites.
Here, we look at some familiar claims made to dismiss Leicester's shock title bid - and check the stats to see if they still have substance...
They can't keep this form up
There has been a season-long assumption that Leicester will eventually fall away. "This week, Leicester will lose," has been repeated throughout the campaign. And yet, with just 13 matchdays to go, they remain top of the Premier League.
Leicester have only lost two out of 25 games - the fewest number of defeats in the league. This is no longer a 'good start' or an 'impressive run of form'. This is the consistency of champions.
Leicester's victory at Man City was the third time they've won three in a row. They've scored first in matches 16 times - a league high - and gone on to seal three points on 13 occasions. They've clinically despatched opponent after opponent.
What's more, they have nothing to fear from their remaining fixtures. Against the opponents they still have to face this season, Leicester have beaten 10, drawn with two and only lost to Arsenal.
They won't beat the big teams
Leicester's ability to win the big games can no longer be questioned. Their impressive 3-1 win at Man City was emphatic. It came on the back of victories over Tottenham and Liverpool - both fixtures billed as tests of Leicester's title credentials.
The Foxes still have Arsenal, Manchester United and Chelsea to face but they took four points from those three games earlier in the season. A repeat would be a substantial step towards the title - especially considering, of the rest of their remaining opponents, Watford, West Ham and Southampton are the only other sides currently in the top half.
Once they get injuries to key players, it will all unravel
Unquestionably, Leicester's unexpected title bid has been boosted by their remarkable injury record. The Foxes have suffered the fourth-fewest number of injuries in the Premier League this season. Claudio Ranieri's squad has been affected by just 15 separate injuries, ahead of this weekend.
In contrast, title rivals Manchester City have had the worst injury record, suffering 51 injuries, while Manchester United (40 injuries), Tottenham (28) and Arsenal (22) have had far more problems than the Foxes.
Injuries to Jamie Vardy and Riyad Mahrez - who have been available for every Premier League match this season - would no doubt reduce Leicester's attacking threat. Ranieri will be hoping his luck with injuries lasts a little longer.
They can't keep up their high-energy performances for a whole season
Tireless running has been a key characteristic of this Leicester team. Their work rate is among the highest in the league - as a team, they covered 4.5km more than Manchester City on Saturday. Surely they can't keep it up?
While the 108.7km Leicester covered at Man City on Saturday was actually 2km down on their season average of 110.7km per game, they have exceeded that average in four of their past six Premier League games - including a 117.3km effort at home to Bournemouth, their second-highest total this season. Leicester aren't slowing down.
Leicester have plenty of time to recover from their weekly exertions, too. Out of the FA Cup and League Cup, and with no European commitments, Leicester have just 13 games left to concentrate on this season - a potentially crucial advantage over their title rivals.
In contrast, Man City have a potential 25 games remaining, with their Capital One Cup final, Champions League knockout phase and FA Cup run keeping them occupied. Tottenham have one more than that, with up to nine Europa League ties and four FA Cup contests taking their tally to 26.
Arsenal could also have 24 games to consider, should their FA Cup and Champions League involvement continue. All of which, plays into the hands of Leicester.
Their rivals for the title are much better
Leicester's title rivals are regulars at the top end of the table. Manchester City have won two of the past four Premier Leagues, Arsenal haven't finished below fourth since 1996 and, in the past six seasons, Tottenham haven't ended a campaign outside of the top six.
Yet, across the pitch, Leicester's players are at least matching the best their fellow top-four sides have to offer this season.
Jamie Vardy is the Premier League's top scorer with 18 goals, Riyad Mahrez is the first player in the top flight to reach double figures for both goals and assists (14 goals, 10 assists), no top-four defender has won more tackles than Christian Fuchs (45) or made as many blocks as Wes Morgan (25), while, in midfield, N'Golo Kante tops the Premier League for interceptions (103).
Conclusion
Leicester can no longer be discounted. Approaching the final quarter of the season, they have a significant advantage over the rest of the top four and the stats underline how well they've been performing.
Whether Ranieri's side can go on to lift the crown remains to be seen. It would certainly be the most incredible Premier League victory ever. But what isn't in doubt, is that right now Leicester are answering all of the questions asked of them.
