Chelsea's relatively young core group of players have had great success since being trusted with first team football in 2019 under Frank Lampard.
Mason Mount and Reece James fronted a set of players that had little to no Premier League experience but were still given the chance to prove themselves on the highest stage. Since Lampard's arrival, the club has played in seven cup finals.
This itself would be classed as success for most clubs. Constantly competing for domestic trophies is a stage that Chelsea have been sat on for a long time. However, of those seven finals the Blues only won three and none of them came in the three domestic showpieces.
