Lampard took it all in his stride, of course, transitioning effortlessly from clapping the songs directed at him to vigorously applauding his Derby players as they hassled and harried Chelsea into defensive mistakes.
It was a mad old night, especially a chaotic, compelling first half, with Chelsea benefiting from two own goals, prompting Derby's magnificent 4,100 fans in the shed to ask politely of their hosts, "Shall we score a goal for you?" Last time out, the Blues put on a strong XI to face Liverpool but could give Callum Hudson-Odoi his first start of the season as the games come thick and fast. Scott Carson couldn't keep out Cesc Fabregas' low-effort, but the visitors felt that Alvaro Morata was blocking his view in an offside position, and that Tom Lawrence was fouled in the build-up to the goal.
Chelsea welcome back a club legend in the Carabao Cup on Wednesday evening when Frank Lampard and his Derby County side head to Stamford Bridge, but the Blues will be without their superstar Eden Hazard.
"On current form, I think he is".
According to a UK Sun report, Lampard insists that the 27-year-old's current form under Italian manager, Maurizio Sarri is far better than that of Argentina's Lionel Messi. "The aim is to come up and play in the Premier League".
Despite the defeat that knocked them out of the competition, Lampard and his Derby County side can keep their head up high and brimming with pride as they put in a performance that was the ideal testament to their ambition under the new manager. "If we relax that then we are not the team we want to be".
But Chelsea fans have been keeping a close eye on the clubs top goal-scorer's success as Derby manager.
Despite the gulf in stature of recent times, Derby and Chelsea have had a fairly equal record in their past meetings.
Chelsea - who made eight changes for the game but still fielded 11 internationals - were ahead again before the break, but it wasn't without controversy. This was not how he had envisaged scoring his first Chelsea goal in front of the Shed End. But, thankfully, the draw for the quarter-finals will occur directly following Chelsea's game against Derby County on Sky Sports, live from Stamford Bridge.
Chelsea was drawn to play Bournemouth at home in the quarterfinals.
"We have two massive games coming up but we can never relax". But now they have gone out and they can concentrate on the Championship, which is what is so important now.
GK Willy Caballero, 6 - Could do nothing about either of Derby's goals, but his distribution was poor and nothing about him inspired confidence in his defenders.
