Chelsea mark their return to the Champions League under new manager Frank Lampard with a home tie against Spanish side Valencia.
Having won the competition as a player in 2012, the 41-year-old makes his managerial debut in the competition against the side the Blues beat on their way to their maiden Champions League triumph.
The Liga outfit have been left in disarray after the departure of coach Marcelino with Albert Celades taking charge of the team for their heavy 5-2 defeat to Barcelona on Saturday.
Things are looking up for Lampard's side after an emphatic victory by the same scoreline against Wolves at Molineux, with Tammy Abraham scoring a hat-trick to make it seven goals in five games.

Prediction: Chelsea 2-1 Valencia
Both teams are at very different stages in their respective seasons with Chelsea scoring five while Valencia conceded that many in their previous game.
Youngsters Tammy Abraham and Mason Mount have set the Premier League alight with some dazzling displays and American winger Christian Pulisic could impress on the European stage if given the chance.

Scoring goals hasn't been a problem for Lampard's men, but the fact they have conceded 13 in just six games under Lampard.
That could give Valencia some hope in grabbing at least one goal at Stamford Bridge, although the Blues are expected to come through their first European test with a narrow victory.

Head to head (h2h) results and history

KICK OFF!

The last time
Chelsea won this match by a 3-0 scoreline back in December 2011 and that proved to be crucial in helping them qualify from their group on their way to their maiden Champions League triumph.
Surely we won't see a repeat tonight?
English trio out to impress

Tammy Abraham, Mason Mount and Fikayo Tomori all scored in the 5-2 win over Wolves and make their European bows tonight.
How times have changed. Once upon a time, it was a miracle just to see an English player get some minutes in a blue shirt. Now we've got three starting!
Zouma in for Rudiger; Cheryshev starts for Valencia
Chelsea manager Frank Lampard has recalled Kurt Zouma to his starting XI for the Champions League opener against Valencia.
The France international replaces Antonio Rudiger after the German suffered an injury on his return from a knee problem.
Otherwise, the Blues remain unchanged from the 5-2 win over Wolves on Saturday.
Goncalo Guedes starts on the bench after sustaining a knock against Barcelona and that means Denis Cheryshev replaces the Portuguese in the starting line-up.
Valencia team news
Starting XI: Cillessen; Wass, Gabriel, Garay, Gaya; Kondogbia, Coquelin, Parejo; Cheryshev, Gameiro, Rodrigo.
Subs: Domenech, Jaume Costa, Guedes, Diakhaby, Lee, Ferran Torres, Gomez.
Chelsea team news
Starting XI: Kepa; Zouma, Christensen, Tomori; Azpilicueta, Jorginho, Kovacic, Alonso; Willian, Abraham, Mount.
Subs: Caballero, Barkley, Pedro, Giroud, Pulisic, Batshuayi, Guehi.
However, the Blues are a new-look side this year with Frank Lampard in charge, and without the magic of Eden Hazard.
Tammy Abraham has made a brilliant start with seven Premier League goals already this season, but Hazard is a big, big loss - and time will tell whether Chelsea have the quality needed to go far in this competition.
So, Chelsea are back in the Champions League after a season away.
The Blues spent that year picking up the Europa League trophy though, and that would have been enough to qualify for this year's Champions League even if they hadn't secured a top-three Premier League finish.
