As for Liverpool, they would have wished the winter break had never existed.
Since they returned, the Reds have been beaten by Atletico Madrid in the Champions League, scraped past West Ham and then tasted a Premier League defeat for the first time in 44 games to Watford - 3-0.
Who can get some momentum going at Stamford Bridge?
Chelsea predicted lineup

Chelsea injury news
Tammy Abraham (ankle), N'Golo Kante (hamstring), Christian Pulisic (abductor) and Callum Hudson-Odoi (thigh) all remain out, and Andreas Christensen (knock) is doubtful, making Frank Lampard's squad looking thin.
Marko van Ginkel (knee) is still out, but Ruben Loftus-Cheek (achilles) has been in the matchday squad in recent weeks, so could make a return.
It's the FA Cup, so you never know what side could be fielded, although Lampard may see this as the time to return Kepa Arrizabalaga to the side, with Willy Caballero taking the number 1 spot since the start of February.
Liverpool predicted lineup
Virgil van Dijk
Liverpool injury news
Jordan Henderson (hamstring), Naby Keita (hip), Xherdan Shaqiri (calf) and Nathaniel Clyne (knee) remain sidelined for the Premier League leaders.
With the unbeaten streak in the league gone, Klopp may feel his side needs to prove a point and could go for a strong outfit.
If he chooses to rotate, Adrian, Joel Matip, Ki-Jana Hoever, Curtis Jones, Alex Oxlade-Chamberlain, Adam Lallana, Takumi Minamino and Divock Origi are all in the frame.
