The European champions remain the only club from London to win the Champions League and now Chelsea made more history.
The Blues are in the driving seat of their last-16 tie with Lille having won the first leg 2-0 on Tuesday night courtesy of goals from Kai Havertz and Christian Pulisic.
And by keeping a clean sheet at Stamford Bridge, Thomas Tuchel's side became the first English team in either the Champions League or European Cup to win five home games in a row without conceding a goal.
Their run dates back to last season when they beat Real Madrid 2-0 in the semi-final second leg to advance 3-1 on aggregate.
Bringing it forward to this season, Chelsea began their home form in Europe with a 1-0 win over Zenit St Petersburg.
An easy 4-0 win over Malmo then followed before a jaw-dropping win against Juventus by the same margin.
The victory over Lille makes it a fantastic five for the Blues who will look to hold on to their two-goal cushion when they travel to France for the return leg on March 16.
