We can't rely on a 38yr old and I honestly think that given recent form it worth given Daka, or even Cannon the starting spot instead.
They're never going to be able to prove themselves without regular opportunities and I honestly think we'd get a better return from Vardy by using him more sparingly for the last 30+ mins rather than constantly flogging the oldest striker in the league for 90 mins every week.
Pretty much every team, apart from Man City, who play with a single striker will replace them almost every game as it is a really tough position yet I'd imagine Vardy has played as many minutes as almost all other strikers, apart from Haaland.
Daka or Cannon could potentially run and chase defenders like a madman for the first 60 mins and then we can bring a fresh Vardy on to work against an already tired defence.
