Chelsea have long been criticised for seemingly stockpiling hot prospects and sending them out on loan after limited first-team opportunities.
A number of stars may consider themselves unfortunate after failing to break through in west London, with a highly-rated youngster recently adding to the growing list of those who have fallen by the wayside.
Despite his rapid rise to becoming one of Serie A's most exciting young players since joining Sassuolo, Chelsea have rejected the chance to trigger Jeremie Boga's buyback clause.
The club, perhaps eager to avoid past mistakes, had inserted a £13million option into the deal to take him to Italy - but they have turned their attentions elsewhere ahead of the upcoming transfer window.
