REF’s picks

Sunderland arrive in Poland with enough quality to secure the three points, even with a handful of notable absentees. Lech Poznań have struggled heavily at this level, underlined by comprehensive defeats to Bayer Leverkusen and Crystal Palace.

1. 1Sunderland's superior squad depth gives them the edge despite injuries to key figures like Brian Brobbey and Daniel Ballard.
2. 2Lech Poznań's defensive vulnerabilities were badly exposed in their European outings, conceding four goals in each defeat.
3. 3The English side could struggle to control the tempo entirely away from home if Lech's forward line finds early rhythm.
