REF’s picks

Sporting CP enter this match with greater continental pedigree and structured poise, making the draw-no-bet safety net on the visitors a sound entry. Lens have shown resilience at the Stade Bollaert-Delelis, but defensive lapses against high-pressing opponents remain a concern. Backing Sporting with the insurance of a refunded stake on a stalemate gives us the right balance of value and security.

1. 1Sporting boast sharp attacking options led by Fotis Ioannidis and solid tactical organisation.
2. 2Lens miss several squad members including Abdallah Sima and Jhoanner Chávez, which limits their depth.
3. 3Sporting's recent domestic draws against sides like Arouca and Famalicão show they can occasionally stall on the road.
