The Blues will head to The Emirates on 29 December as Frank Lampard’s men come up against their London rivals in the English top flight.
David Luiz has been settling into life at Arsenal after having opted to leave Chelsea FC and sign for the Gunners in the summer transfer window.
The defender has started all but one of Arsenal’s Premier League games so far this season.
Willian and David Luiz have played together for many years for both club and country – but they will now face each other twice in the space of a month, with Arsenal also travelling to Stamford Bridge in the Premier League on 21 January.
Willian has described David Luiz as his “brother” but says that won’t stop him performance against him when Chelsea FC take on the Gunners.
Speaking in an interview quoted by Metro, Willian said: “I’ve faced him a few times, he for Chelsea, me for Shakthar, me for Chelsea, he for PSG.
“Now it’s he for Arsenal. He’s a brother that I have, we met at the age of eight.
“But on the pitch… there’s no way. If I have to nutmeg him, I will.”
Chelsea FC will return to Premier League action on Saturday afternoon when they host London rivals West Ham United at Stamford Bridge.
Arsenal, meanwhile, are currently preparing for their trip to Norwich City in the Premier League on Sunday afternoon.
