Pierre-Emerick Aubameyang might make his Chelsea debut away to Dinamo Zagreb.
Prior to his journey to Zagreb, Aubameyang traveled to Milan last weekend for a mask fitting and was able to practice comfortably while wearing it.
Aubameyang was previously anticipated to be out for several weeks, but Tuchel voiced optimism that the forward would return soon in a statement last week.
Denis Zakaria, a different recent acquisition who plays in midfield, is part of the traveling party.
