In a season full of surprises and no standout favourite for the title, Leicester currently lead the way with 32 points from their 15 league games to date, losing just once.
It has been a superb effort so far from the Foxes, especially considering how so many tipped them for relegation following the appointment of Italian boss Claudio Ranieri.
But Merson doesn’t believe it will last, citing their lack of squad depth as why they can’t sustain it.
“Leicester are not winning the league. If they get in the top six at the end of the season they’ll have pulled up trees,” Merson wrote in his column for the Daily Star.
“Leicester’s players all know their jobs, they do exactly what’s asked of them and Jamie Vardy scores the goals.”
“But let’s be honest, they play the same XI every game and they have to play out of their skins to win a football match. That catches up with you in the end.”
“What happens if Vardy or Drinkwater or Mahrez get injured? What happens if all three do? At the moment they’re living the dream. But that’s exactly what Leicester winning the league is – a dream.”
Leicester have a tough set of fixtures coming up with trips to Everton and Liverpool sandwiched between two home clashes with the pre-season title favourites Chelsea and Manchester City.
The Foxes are reliable on goal scorers Jamie Vardy and Riyad Mahrez, but that doesn’t mean they lack quality elsewhere as Danny Drinkwater and N’Golo Kante among others are playing superbly.
The closeness of the top four suggests that Leicester could find themselves knocked off top spot over the next few weeks but they hold a healthy nine-point gap over sixth-placed Crystal Palace.
European football is undoubtedly now a realistic target for the East Midlands outfit and if they can keep hold of their better players in January, there is no reason why they can’t achieve it.
