Leicester City boss Claudio Ranieri insists they're proof that money can't buy success.
The Foxes will win the league with victory at Manchester United on Sunday in one of the most extraordinary seasons in modern football.
Ranieri said: "Once in the life it can happen. That is football. Once every 50 years a little team with less money can beat the biggest ones.
"If there are 20 teams who spend millions of pounds at the end of the season one will win the title and three will go down.
"Now there are very special circumstances. The big teams don't have the consistency and normal teams have the consistency during the season.
"From August to April and now it's important to keep the same consistency in May.
"I'm waiting for next season, United at the top, Chelsea at the top, Liverpool, (Manchester) City and Arsenal and we are fighting."
