The Foxes beat Southampton 1-0 last time out and are close to pulling off a footballing miracle after going seven points clear at the top of the table with just six games to play.
They could even go 10 points clear of nearest rivals Tottenham Hotspur should they beat relegation battlers Sunderland in the lunchtime kick-off on Sunday ahead of Spurs' game against Manchester United.
Claudio Ranieri's men have been the fairytale story of a lifetime with their rise from relegation certs to title challengers this season.
And fans all over the country have been willing them on to break the monotony of the established Premier League elite.
With the likes of Riyad Mahrez, N'Golo Kante and Jamie Vardy in scintillating form all season long the Foxes have won more games than any other side and lost fewer too.
'To me Leicester aren't even a good team'
"There's a part of me that looks at Leicester, and they don't impress me... they do not impress me," Quinn said on talkSPORT.
"I've probably seen a couple of good performances from them.
"Especially the last three, four games I don't think they've even played well.
"There's a professionalism in me that says I admire them lads like Jamie Vardy five years ago playing in the eighth tier of football... and the lads they've got that were released from other clubs, the professional side of me really admires them for where they are.
"But in what is probably the poxiest Premier League since it started it, they're leading it, now what reflection is that for us next season if they're in the Champions League?
"To me the credibility of the Premier League would be for Spurs to come and pip them at the post... to me Leicester aren't even a good team."
If anything the polar opposite is true
While Quinn is entitled to his opinion, it is one that is sure to stick in the craw of not only Foxes fans but most neutrals who have been rooting for them.
If anything the complete opposite of what Quinn saying is true, Leicester winning the title would be the best thing to happen to English football for decades.
And who is to say the Foxes can't be successful on the European stage?
They have an experienced manager who has worked in top jobs across the continent and some top players.
The club, buoyed by massively increased revenue streams, will also surely be very active in the summer transfer market and will also have the added carrot of Champions League football, where they will be seeded too.
Quinn talks about Leicester's last few games, where they have had to grind out 1-0 wins, disparagingly.
But you can be sure if it was one of the established elite he would be using the same stats about the 1-0 wins to praise say an Arsenal for example for showing great grit and determination.
After all they pundits always say grinding out wins when you're not playing well is the true sign of champions.
