Redknapp was joined in the studio at Stamford Bridge by former Chelsea striker Jimmy Floyd Hasselbaink, who was impressed with the way his former team-mate Lampard set Derby up to give Chelsea problems.
When is Chelsea vs Derby County? 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. "I'm sure he'll be up for it and it will be important to get even more indications for us".
It was a special night for the manager who returned to Stamford Bridge for the first time tonight as a manager.
"On current form, I think he is". "I was analysing the players we had on loan". "To deal with that, with all eyes on him at Chelsea, at his parent club, his recovery under that pressure was brilliant".
However, in a "gesture of goodwill", Chelsea announced that their Derby loanees Mason Mount and Fikayo Tomori will be allowed to play against them in the club's Carabao cup tie at Stamford Bridge on Wednesday night.
"We have two massive games coming up but we can never relax". Sarri may look to make the most of the chance of playing at home to a team from the Sky Bet Championship and hand the experienced Argentine his second start of the season.More news: OxygenOS Open Beta 6 brings Nightscape and more to OnePlus 6
Chelsea are still unbeaten in domestic competition this season, and despite their potential absentees they will be looking to come through against Derby and move into the quarter final of the competition. Tomorrow we are going to decide whether he is going to be part of the team'.
41' - GOAL! Chelsea 3-2 Derby: For the third time Chelsea lead this evening, but Derby aren't happy. Mount endured no such humiliation, instead building on a slightly over-eager start to provide an impressive assist and help power Derby's late surge.
The lead was short lived as Mason Mount, another Blues loanee, laid on Martyn Waghorn's leveller after 27 minutes. "But he was asked to produce moments, and he did".
7 - Sarri gave many of his frustrated reserves an opportunity and was nearly let down, but deserves credit for whatever he said at half-time. It was his pass for the second goal.
That status belonged to the returning legend, honoured for his past by Stamford Bridge and for his present by the young team whose performance did him such credit. Marriott slips through Nugent and his shot from an acute angle beats Caballero but cannons off the post and bounces back to into the safe arms of the Chelsea goalkeeper.
Similarly, in the dugout, Lampard is in the early stages of a career that could take him to the top once again.
