Following last Friday's 1-1 draw at the CFA Jason Wilcox's men arrived at Stamford Bridge looking to gain the upper hand on Joe Edwards' boys who are recent UEFA Youth League winners and holders of the last two FA Youth Cups.
City enjoyed the best of the first half and played with much greater intensity than the first leg at the CFA, Isaac Buckley-Ricketts utilising space on the right flank to great effect, his fizzing cross narrowly evading the on rushing Lukas Nmecha.
Chelsea's first real chance came on 21 minutes, Abraham fought off Cameron Humphreys though he stabbed his shot high and wide from eight yards out. Joel Latibeaudiere bowed out of the tie on 25 minutes as what appeared to be a dislocation of the shoulder forced him off, Marcus Wood his replacement.
Soon after Jay Dasilva was called upon as Nemane burst down the wing and his dangerous low cross needed to be cleared for a corner, the resulting corner a fairly poor one. Buckley once again giving Chelsea plenty to think about, an excellent piece of close control saw Dasilva stumbling, though the deep cross that followed was cleared. First card of the night went to the hosts, Mukhtar Ali with a clumsy challenge on Jacob Davenport saw him first in Mark Tierney's book.
An excellent break from Chelsea saw Mount played through by Abraham though his shot was dragged wide of Daniel Grimshaw's far post, Chelsea's resurgencey emphasised with another effort minutes later that needed intervention from Humphreys to block and clear.
Hosts score goal late in first half
Seconds before the final whistle the hosts took advantage, a miscommunication between Tosin Adarabioyo and Grimshaw saw Dujon Sterling pounce on the ball, round Grimshaw and slot home. HT Chelsea 1-0 Manchester City (Agg. 2-1)
Chelsea got the second half underway with heavy spell of hail setting in over West London, but it was City with the first chance. Once again Buckley's cross a superb one which Nathan Baxter attempted to smother but broke lose needing a hasty clearance to prevent Nmecha from following up. A fantastic challenge from Wood denied Abraham at the other end from making it 2-0 on the night the resulting corner dealt with comfortably.
City thought they'd found their equaliser on 51 minutes, Buckley's cross parried by Baxter was then finished by Nmecha, the linesman however decreed as offside.
Chelsea put match to rest
Moments later Chelsea furthered their lead, 54 minutes gone Abrahams' looping header sneaked in at the far post deceiving Grimshaw who thought it was sailing over.
Isaac Christie-Davies was replaced by Sam Maddox and Nemane made way for Jadon Sancho 64 minutes gone. Grimshaw was on hand to deny Dasilva at his near post, the full backs ferocious shot cleared for two successive corners the second producing Chelsea's third of the night, Fikayo Timori towering above the City defend to nod home, putting the tie out of City's reach 15 minutes remaining. Adarabioyo was replaced shortly after by Tom Dele-Bishiru. Joshua Grant replacing Trevor Chalobah.
Into the final ten minutes and it was a case of damage limitation now for City with Chelsea looking to make it a comprehensive rout. The final Chelsea substitute saw Sterling vacate for Ike Ugbo. A consolation goal for City arrived with three minutes remaining, Brahim Diaz slotting home following a corner but it was all too little too late as Chelsea saw out the remainders of the tie with ease, retaining the FA Youth Cup for another year.
