Chelsea attacker Kai Havertz is missing for tonight's FA Cup tie at Barnsley.
The German has been absent from the Blues' last two games after sustaining a knock early on in Thomas Tuchel's tenure.
Last week, Tuchel described Havertz as having a 'little issue'.
But the £70million summer signing is yet to return to the training field.
A number of youngsters will be hoping for involvement, having been given a taste of first-team training by Tuchel this week.
Exciting starlets Lewis Bate, Levi Colvill, Tino Livramento and Tino Anjorin were all put through their paces by Chelsea's new boss yesterday.
