Since Chelsea last played Bournemouth, they have started £20m summer signing Carney Chukwuemeka just twice. Those games both came nearly five months ago.
The 19-year-old has had his progression halted after appearing as one of the few positives over a dark winter period for the Blues. He almost opened his account in a 1-1 draw with Manchester United and also came close against Manchester City.
He built up a small run of league games at a time that injuries plagued Graham Potter's squad but looked settled in a team that was faltering. His energy, drive and decisive final third choices were a breath of fresh air in an otherwise dour team.
