Riyad Mahrez scored twice as holders Manchester City came from behind to thrash League One Wycombe and reach the last 16 of the Carabao Cup.
The visitors took a shock lead through Brandon Hanlan, but Kevin de Bruyne levelled seven minutes later.
Mahrez claimed his double either side of half-time, with Phil Foden and Ferran Torres also beating veteran goalkeeper David Stockdale.
Substitute Cole Palmer, 19, added the sixth with his first goal for the club.
He ran from the halfway line before curling in a fine left-footed shot from 20 yards.
It was a successful night all round for City's youngsters, with Pep Guardiola handing senior debuts to academy graduates Conrad Egan-Riley, Luke Mbete, Finley Burns, Josh Wilson-Esbrand and Romeo Lavia.
Defender Wilson-Esbrand was particularly impressive, with his excellent control and cut-back assisting Mahrez for City's second strike.
