Frank Lampard threw another spanner in the works when he started three at the back for Chelsea against Wolves at the weekend.
The experiment certainly paid off, however, after a 5-2 victory, and the Blues boss might be willing to do it once again tomorrow night.
Chelsea gets their Champions League campaign underway at Stamford Bridge against Valencia, with the Spanish side going through some turmoil themselves after sacking their manager last week.
The Blues will be confident going into the game, however, will have to play the match without N’Golo Kante, Antonio Rudiger, Callum Hudson-Odoi and Reece James, who is not yet fully fit.
“Toni [Rudiger] is injured,” Lampard said. “He bothered a small groin injury that he has been carrying in the last couple of weeks, at the weekend, so he is out. He will have a scan today to see where he is, hopefully, it’s not long term.
“The other three [Kante, Hudson-Odoi, James] are fit, but not match fit. Callum is getting extra work in, along with Reece and they may have another game in the U23s before the first-team action.
“N’Golo similarly, not to play in the 23s, but he will have more training to do because the injury has been bothering him a bit.”
If Lampard goes for three at the back again, then it will be Kurt Zouma, Andreas Christensen and Fikayo Tomori playing in defense, with Cesar Azpilicueta and Marcos Alonso as wing-backs.
Meanwhile, Mateo Kovacic and Jorginho will play in the middle of the park, with Mason Mount and, potentially, Pedro on the wings.
Tammy Abraham could well keep his goalscoring form going if given the nod ahead of Olivier Giroud and Michy Batshuayi.
Predicted Chelsea team (3-4-2-1): Kepa; Azpilicueta, Zouma, Christensen, Tomori, Alonso; Kovacic, Jorginho; Pedro, Abraham, Mount.
