Christopher Nkunku, Andrey Santos, Malo Gusto and any returning loanees will all be added to Chelsea's squad for next season. It could take the initial number of players up to nearly 40. For the new coach, heavily expected to be Mauricio Pochettino, it poses a massive question.
It is also a challenge. How to deal with it, who to cut from the group, just what number is the happy medium to provide squad depth but not too much and is this all possible? It's certainly a big task. This is without factoring in more arrivals coming in during the transfer window.
These are widely covered issues that face the prospective new boss at SW6. Another big sliding doors problem is the unknown future for Mason Mount. Whilst the season enters its final weeks the 24-year-old is recovering from injury. All of this comes whilst his contract prepares to enter the final 12 months.
