Leicester City winning the Premier League could be football's "biggest story", according to Jamie Carragher.
A Jamie Vardy double secured Leicester's 2-0 win over Sunderland and sent the Foxes 10-points clear of second-placed Tottenham, before Spurs narrowed the gap to seven points with an emphatic 3-0 win over Manchester United at White Hart Lane on Super Sunday.
Sky Sports pundit Carragher believes Leicester will hold on to lift the Premier League title and eclipse Nottingham Forest's European Cup-winning side.
"Is it the biggest story we've seen in football? There's obviously Nottingham Forest when they went on to win European Cups and I think it's safe to say we won't see Leicester do that," Carragher said.
"But the days of someone coming up or a smaller team winning the league was more likely to happen in the 60s, 70s, 80s.
"The top four was normally set in stone, certainly when I was playing. No one ever made a fist for that. This, to think where they've come from, could be the biggest story in football we've ever seen.
"Ranieri said before the game this could happen in 50 or 60 years' time. The chances of seeing something like this again? I think it could be double that."
Leicester's win at the Stadium of Light guaranteed them a top-four spot just 12 months after they flirted with relegation to the Championship.
Graeme Souness said Leicester now had "one hand on the trophy" and their success would inspire other clubs mount title challenges of their own in the future.
"It's the most incredible story in the Premier League's history," Souness said.
"Such a small team getting themselves so far in front, being top of the league for so long, playing with great resilience, not always easy on the eye to watch.
"The type of football you thought was a thing of the past where it's get the ball forward as quickly as you can for a striker who at 29 is very unusual in that he wants to run in behind all the time.
"A year when all the big teams have tripped up I think it is the most interesting, fascinating Premier League ever and I think they've won it now.
"I think it is the most wonderful thing for football, it gives everyone out there who's not a big boy, not one of the big boys, think 'we can do that'. They won't, but they will think they can."
