Leicester City grabbed the Premier League lead temporarily by beating Chelsea 2-0 during their match on Tuesday in the 18th round of the competition.
Leicester advanced with a goal scored by Wilfred Ndidi in the sixth minute, and James Madison added the second goal in the 41st minute.
Leicester City raised its score to 38 points at the top of the standings, one point ahead of Manchester United, who later faces Fulham, and Chelsea's score stopped at 29 points in eighth place.
This is the 12th victory for Leicester in the league this season compared to a loss in 5 games and a draw in two games, while this loss became Chelsea's sixth in the league this season in exchange for a win in 8 games and a draw in 8.
The loss doubled the pressure on Chelsea coach Frank Lampard, who faces widespread criticism over the team's performance, despite spending more than 200 million euros to sign new players.
Speculation about the future of Lampard increased, and English press reports spoke of the possibility of his dismissal in the coming days to avoid a further deterioration in the results.
