Leicester boss Claudio Ranieri has confirmed his deadly duo of Jamie Vardy and Riyad Mahrez are not for sale, after his side returned to the top of the Premier League with a convincing 2-1 win over relegation-battlers Chelsea. Vardy scored his 15th goal of the season from Mahrez's cross before Mahrez himself scored with a fantastic strike.

"No-one can buy Vardy or Mahrez in January," said Ranieri. "They don't have the money".

When asked how much the players were worth to him, the former Chelsea boss said: "I don't want to put a price on them... for me they don't have a price".

Vardy arrived at Leicester for a fee in the region of £1m ($1.5m) following a progression up from non-league football, while Mahrez was signed for £400,000 two years later in January 2014.

"I told my players, five more points and we are safe," said Ranieri. "I put that target at the beginning of the season, and when we achieve 40 points, we will change our goal.

"There was a lot of electricity tonight, without that we are a normal team but with the fans pushing us we are very happy. They continue to dream but we must continue to keep our feet on the ground.

"It's a magical time, we must continue to work hard because I don't want to wake up. I want to continue to dream with our fans."
