The 40-year-old already has a giant-killing to his name as Derby boss, having overseen their thrilling penalty shootout win over Manchester United in the third round of the EFL Cup.
If Derby do end up knocking out Chelsea, there would surely be different questions being asked of the club, as is the work of the fans and pundits, so it is best to leave their business alone. The more they play against Premier League teams the more experience they get.
Adding to the atmosphere is the fact that it's highly unlikely that Lampard and Morris will engage in any kind of fan-angering behaviour the way former Chelsea manager and one-time idol Jose Mourinho resorted to recently when his Man United side played at the Bridge; all things being equal, there's little chance of abuse being directed their way should they mastermind a victory for the visitors.
The duo complement each other extremely well and they have competently nudged Derby into the Championship playoff places. "I thought he handled it really well".
Gianfranco Zola afterwards played down the notion that Chelsea's edge had been blunted by playing in a stadium chanting for the opposition manager, instead crediting Lampard's game plan of blocking passes into Cesc Fabregas and forcing those behind him into uncomfortable decisions.
Chelsea loanee Fikayo Tomori put through his own net during the opening exchanges, but had his blushes spared by Jack Marriott who drew the game level.
Chelsea: Caballero 6, Zappacosta 7, Cahill 5, Christensen 5, Emerson 6, Kante 6, Fabregas 7, Kovacic 6, Loftus-Cheek 8, Morata 5, Willian 7. As a result, Chelsea have allowed Mount and Tomori to be available for selection by Derby to face them at Stamford Bridge on Wednesday. Subs: Forsyth 5, Bennett 5, Nugent 6.
Key Stat: Chelsea have conceded three goals in their past three matches across all competitions.
Yet while Derby were obliging, they always carried a potent threat of their own with Mount and Harry Wilson pesky.
Ruben Loftus-Cheek is now enjoying the best goalscoring spell of his career, netting in two consecutive games for the first time.
The last time Frank Lampard walked onto the Stamford Bridge pitch in away colours, he was booed.
FW Ruben Loftus-Cheek, 7 - Deployed on the right wing just as he was against Burnley on Sunday, the academy graduate was Chelsea's best attacking performer on the night. Chelsea won 6-1 on that occasion as the Rams were on they way back down to the Championship.
"The difference between the sides was they scored three - actually we scored four didn't we?"
