Real Sociedad have a number of fitness concerns ahead of tonight's Champions League clash against Bayer Leverkusen in Spain.

The La Liga outfit cannot quality for the knockout stages of the competition, but can play a part in determining who qualify alongside Manchester United in Group A.

Alberto de La Bella is certain to miss out with a toe injury that has kept him on the sidelines for eight weeks, while David Zurutuza is also expected to sit out with a knee sprain.

However, a number of fresh injuries have harmed their preparation over the past few days with key defenders Inigo Martinez and Dani Estrada struggling with thigh and foot problems respectively.
