Leeds United remain in the Premier League relegation zone with two games to go after losing to Chelsea, who are closing in on sealing a Champions League spot.
Mason Mount scored the game's opening goal with a lovely first-time effort from outside the box from Reece James' cut-back at the end of a nice passing move.
United had Daniel James sent off for a dangerous high tackle on Mateo Kovacic, who had to be replaced. They later became the first team to ever receive 100 yellow or red cards in a Premier League season.
Christian Pulisic slotted Mount's pass into the bottom corner from 20 yards.
