Frank Lampard has confirmed Chelsea could be without the trio of Hakim Ziyech, Ben Chilwell and Reece James for their Boxing Day clash against Arsenal.
Ziyech has struggled with injuries since moving to Chelsea for £33.4million this summer, last appearing in their 3-1 win against Leeds earlier this month.
The Moroccan playmaker picked up a knock in that game having played a crucial role in Olivier Giroud's equaliser, and Lampard says he is still not ready to return.
'No, he won't be fit for Arsenal,' he said ahead of the London derby.
