The apprentice has become the master at Old Trafford as Frank Lampard saw his Derby County side stun 10-man Manchester United in a penalty shoot-out after a thrilling 2-2 draw at Old Trafford.
Lampard was a star in his playing days under Jose Mourinho at Chelsea but the Portuguese will not be thanking his former midfielder after Derby inflicted a chastening Carabao Cup defeat.
The result enhances Lampard’s burgeoning managerial reputation following his solid start to life in the Championship but it is a damaging loss for Mourinho just hours after news emerged that he told Paul Pogba that the star midfielder will never captain the club again.

And United only have themselves to blame after they sat back and let Derby dictate play after Juan Mata had given them the lead in just the third minute.
It looked to have cost them a place in the fourth round when Derby scored two second half goals through Jack Marriott and a wonderful 35-yard free kick from Harry Wilson. In between those goals, United had goalkeeper Sergio Romero sent off for deliberately handling the ball outside the box.
However, Marouane Fellaini sent the match to penalties in injury time when he rose highest to head home Diogo Dalot’s right-wing cross.
But Lampard was not to be denied a famous win on his return to Old Trafford.
After a marathon shoot-out which saw 15 consecutive penalties scored, goalkeeper Scott Carson stepped up to save Phil Jones’ effort to ensure Derby won 8-7.
Mourinho took the opportunity to rotate his squad, making nine changes in all, but he still named a strong side for Frank Lampard’s visit.
Ashley Young captained the side in Paul Pogba’s absence as Romero started in goal and 19-year-old Dalot started at right back, while Anthony Martial earned a recall. Only Romelu Lukaku and Jesse Lingard kept their spots from Saturday’s draw with Wolves.
It was Lukaku who almost gave United the lead inside 90 seconds but his glancing header was well saved by Carson.
United had no time to rue that chance though, as they took the lead barely a minute later through a brilliantly-worked, fluid team goal.
Martial crossed from the left, and sumptuous one-touch passes from Lukaku and then Lingard combined to put Mata in space on the right and the Spaniard swept home with aplomb.
However, Derby almost hit back immediately.
Mason Bennett was picked out at the far post with a sublime, defence-splitting pass from on-loan Chelsea midfielder Mason Mount, but the midfielder’s close-range shot was well saved by Romero.
Mata then almost had a second when he sprung Derby’s off-side trap but Carson was equal to his spin and shot.
Lukaku should then have doubled their lead after running clean through on goal, but he sent his shot wide. The big Belgian then completed his hat-trick of missed chances when he headed over, under pressure, from two yards out.
The second half started in much the same vein with Derby edging possession and United looking threatening on the break. In a rare clear-cut chance Liverpool loanee Harry Wilson almost hauled Derby level but his powerful shot was just turned around the corner by Romero.
It was going to take something special to break down United, and Wilson obliged on the hour mark.
There seemed little danger as he stood over a free kick 35 yards out, but the Liverpool loanee fired a stunning shot into the top corner, the ball bending right and then left, leaving Romero with no chance.
The goal gave Derby renewed confidence but the game was turned on its head when Romero was sent off for his handball. The Red Devils’ goalkeeper had come steaming off his line to deal with a long ball but was beaten to it by Wilson and was rightly red carded when he stuck out his left hand to stop the ball going past him.
Going down to 10 men finally roused Manchester United and the game opened up. There was an urgency from the Red Devils not seen all night and they were almost rewarded when Lukaku fired a shot against the post and then Martial sent a follow up wide.
Derby almost took the lead but replacement goalkeeper Lee Grant’s fingertips kept out Florian Jozefzoon’s well-placed header.
But the stopper could do little to prevent Derby taking the lead with five minutes to go.
Grant did well to keep out Mount’s shot from the edge of the box but he could only push the ball into the path of substitute Jack Marriott, who gave Derby the lead despite the keeper getting a hand to his header.
VAR was consulted but Wilson, in an off-side position was deemed to not be in play despite being close Marriott’s shot.
However, with Lampard and the Derby fans sensing a famous victory second-half sub Fellaini rose highest to equalise in injury time and send the match to penalties.
But in the end Fellaini’s header only extended the agony for United as Derby won the marathon shoot-out 8-7 and recorded a famous win in front the Stretford End.
