If Mykhailo Mudryk receives a lengthy ban, Enzo Maresca is expected to invade the January transfer market.
Following a positive test for the prohibited drug meldonium, the Chelsea manager is standing by his winger.
Mudryk, who maintains his innocence, is awaiting the findings of a "B" sample that was obtained while he was serving in Ukraine.
Under their present ownership, Chelsea has spent over £1 billion.
Meldonium, a substance thought to enhance performance, was detected in tiny amounts in Mudryk's urine.
The 23-year-old wide player, who faces a maximum four-year ban if convicted, says he is shocked by the results.
Despite having an abundance of wingers, Chelsea has a good chance of winning both the Premier League and the European trophy this year.
If Mudryk has a lengthy suspension, Tyrique George, a homegrown player, is most likely to be promoted.
