Frank Lampard elected to switch to a back-four system for his first game back in charge of Chelsea at the weekend.
The decision perhaps inevitably backfired for the Blues, as they were defeated 1-0 by Wolves in a game they would have been hoping to build momentum in.

After resting a number of key players, all eyes now turn to the Champions League tie against Real Madrid tomorrow night.
With a new system surely on the way, here is the Chelsea Chronicle’s predicted XI for the Champions League quarter-final.
GK and Defence

Despite previous situations seeing Kepa Arrizabalaga dropped by Frank Lampard, he will continue for the huge match tomorrow.
Reece James is likely the first name on the teamsheet tomorrow night, and will look to carry on his battle with Vinicius Jr.
A return to a back-three will see Wesley Fofana back to the right of defence after an impressive return from injury.
With Thiago Silva back in training, there may have been a shout for him to start given his importance. However, the game comes to soon, and Kalidou Koulibaly will return.
Benoit Badiashile is of course not available, so it will be another start at centre-back for Marc Cucurella.
After being rested against Wolves, Ben Chilwell will be back amongst the starters for the crucial quarter-final.
Midfield

Enzo Fernandez has started every game since his club-record move in January, and will be there again tomorrow night.
With him being left out of the squad completely against Wolves at the weekend, N’golo Kante will start just his second game since returning from injury.
In a midfield three, Mateo Kovacic will continue despite still not yet committing his future to the Blues.
Attack

Often the man to rely on in the big occasions, Kai Havertz will start up front for the Blues tomorrow.
In a front two, Joao Felix will look to impress and score on the big stage, a rare achievement for this season.
