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.
