REF’s picks

Panathinaikos bring strong continental momentum and home comfort into this fixture, making them clear favourites against a struggling CSKA Sofia side. Despite dealing with a few defensive absences, the Greek outfit's attacking depth should comfortably break down a visiting defence that has leaked goals on the road.

1. 1Panathinaikos have won all five of their recent matches in all competitions, scoring heavily along the way.
2. 2CSKA Sofia arrive on a winless run of four defeats and a draw, showing severe defensive frailties in Europe.
3. 3Key injuries to defensive regulars like Ingason and Kristiansen could occasionally leave the hosts vulnerable to a counter.
