Since Chelsea’s switch to the 3-4-3, David Luiz has been in superb form for Chelsea but he was poor against Tottenham as we lost 2-0 to our London rivals.
The game was a tight affair with both sides failing to get a shot on target until Tottenham scored just before half-time through a header by Dele Alli but if Luiz had done his job properly, maybe we wouldn’t have conceded that goal.
David Luiz’s marking for Tottenham’s first goal was really poor as he left Cesar Apilicueta to mark two players while he stepped out to mark no one in particular.
The photo below shows Luiz had Harry Kane covered before Christian Eriksen’s cross with Cesar Azpilicueta conscious of Dele Alli behind him.
Luiz then wanders towards the ball and left Kane unmarked leaving Azpilicueta to mark two players (Alli and Kane) and Azpilicueta quickly marked Kane and left Alli free in the box.
Victor Moses should also have closed down Alli seeing Azpilicueta had closed down Kane but Moses was also conscious of a free Danny Rose behind him.
David Luiz had no business stepping forward and if he had stayed with his man (Kane), Azpilicueta would have focused on Alli while Moses focused on Rose who was behind him. Luiz stepping out made us have two players marking three Tottenham players inside our box.
Moving away from the mistake from David Luiz, where was the cover for our defence? The picture below also shows four Chelsea players (Cahill, Alonso, Matic, Kante) marking just two Tottenham players (Eriksen and Walker).
