Frank Lampard's biggest and longest-lasting impact at Chelsea as a manager was undoubtedly the effect he had on the club's youth academy. For the first time since Roman Abramovich took over the club a group of shining stars came through at once.
It was partly needed due to the transfer ban imposed, but Lampard's impressive work with inexperienced Championship players at Derby County on loan from the club helped his stock rise. Mason Mount and Fikayo Tomori were handed England call-ups within 12 months of their Chelsea debuts.
Tammy Abraham was the club's top scorer in the first season, netting 15 times from open play, more than any player has managed since 2019/20. Ruben Loftus-Cheek was on loan but Callum Hudson-Odoi was called upon too. Lampard also gave debuts to Reece James - now one of the world's best defenders - as well as Armando Broja, Ian Maatsen and Marc Guehi.
