The battle to advance from Group F remains fierce, with only four points separating Barca, Dortmund and Inter Milan. Barca are in top spot, although they've not been convincing in the Champions League this season - notably being held to a 0-0 draw against Slavia Prague last time out. A victory over Dortmund will see them through to the next phase of the competition as they will not want their future in the balance when travelling to the San Siro in the final round of fixtures. Ernesto Valverde's men have been inconsistent with their performances even outside Europe, needing a comeback to see off Leganes at the weekend.
