REF’s picks

Olympiacos are in excellent form and the atmosphere at the Karaiskákis Stadium is always a major factor in Europe, making them clear favourites here. While their goalscoring might be affected by key injuries, they remain defensively resolute and should have enough to overcome a Sparta Prague side struggling with significant depth issues and a lengthy injury list.

1. 1Olympiacos have won five on the bounce, showing great resilience in tight games.
2. 2Sparta Prague are depleted by injuries to key players like Ryneš and Martinec.
3. 3The handicap line reflects the disparity in current momentum, but a disciplined defensive performance from the visitors remains a risk.
