Leicester captain Wes Morgan believes the Foxes have changed the landscape for future seasons.
Claudio Ranieri’s side are five points clear at the top of the Premier League ahead of Sunday’s trip to title rivals Arsenal.
A 3-1 win at Manchester City last weekend saw them installed as favourites to win the league in one of the most open races for years.
They beat the drop last term by winning seven of their last nine games and were widely tipped for relegation at the start of the season.
But, after a stunning campaign which has so far brought just two league defeats, Morgan feels the Foxes have altered the dynamic of the Premier League.
“It’s a bit of a fairytale, a big surprise to everyone, but we have real belief in ourselves and deserve to be here,” said the centre-back, who still refused to talk about Leicester’s chances of the title.
“In Premier League history you have the top four who tend to be the outstanding teams that beat most of the teams, and this season has been a bit of a change.
“There have been teams promoted from the Championship coming and competing and beating the top teams.
“That dynamic has changed a lot this season and I think it will continue through the seasons coming.
“The so-called bigger teams will have to re-analyse how they go about buying players. If you have spent £100million on a player it doesn’t necessarily mean they are going to bring you the title or bring you success.
“Teams will probably look at us and the likes of Bournemouth and Norwich and think, ‘maybe we need to re-analyse how we go about buying our players and our policy of signing people’.”
Leicester lost 5-2 to Arsenal in September, but Morgan was keen to look forward to Sunday’s match – and the run-in that follows – rather than back at that loss.
“That was the start of the season when everyone is trying to find their way,” the 32-year-old said. “This is the probably the more crunch part of the season and these next few games are going to define where everyone finishes.
“The pressure is definitely on Arsenal to try and prove a point. We relish that and we want to go into the game and show what we are capable of.”
