Jamie Vardy and Riyad Mahrez are not for sale, according to Leicester boss Claudio Ranieri after his side returned to the top of the Premier League with a 2-1 win over Chelsea.
Striker Vardy scored his 15th goal of the season from Mahrez's cross before the Algeria winger netted a superb 11th league goal.
"No-one can buy Vardy or Mahrez in January," said Italian Ranieri, 64.
"They don't have the money and they don't have a price."
Vardy, who is the Premier League's top scorer, was playing non-league football four years ago and arrived at Leicester for about £1m in 2012.
Mahrez was playing in the second tier in France before the Foxes signed him in January 2014 for a reported fee of £400,000.
The pair have been instrumental in Leicester's rise to the top of the league, where they lead second-placed Arsenal by two points.
After 16 games last season Leicester, then managed by Nigel Pearson, were bottom of the league.
