Willian double seemingly set Chelsea Premier League campaign back on track with a 2-0 win at Tottenham in a London derby.
Chelsea’s impressive form under head coach Frank Lampard had tailed away in the time Mourinho reinvigorated Spurs, having succeeded the struggling Mauricio Pochettino last month.
Tottenham would have leapfrogged the Blues into fourth with victory, but Willian two goals before half-time – the second from the penalty spot after a Paulo Gazzaniga error.
Son Heung-min was sent off for kicking out at Antonio Rudiger with 28 minutes left.
Lampard’s men cruised to the finish at Tottenham Hotspur Stadium.
The game was interrupted as referee Anthony Taylor addressed the two coaches, after Rudiger reported an incident of racist abuse.
This win for Chelsea, ensured a four-point buffer to fifth-placed Sheffield United at Christmas – with Mourinho’s Spurs back in seventh.
