Willian’s brace carried Chelsea to a deserved 2-0 victory over 10-man Tottenham – but the spotlight was again fixed on racism after Blues defender Antonio Rudiger was allegedly targeted in the second half.

The attention should have been on Jose Mourinho’s touchline duel with Frank Lampard.

Instead, it was on the stadium announcer, who repeatedly read out: “Racist behaviour among spectators is interfering with the game.”

It also overshadowed a superb showing from Willian, who curled in a delicious opener on 12 minutes before coolly converting a penalty in first-half stoppage time after VAR intervened to punish Paulo Gazzaniga’s clumsy foul on Marcos Alonso.

Son Heung-min was dismissed for a petulant kick on Rudiger on 62 minutes, awarded after another long consultation with VAR, as the home side’s hopes of a fight back were dashed.

The result sees the Blues remain fourth and increase the gap between themselves and seventh-placed Spurs to six points.

Next up, Tottenham host Brighton while Chelsea are at home to Southampton on Boxing Day.
