Barcelona boss Vilanova: We don't need to win at Spartak Moscow
Barca have been rattled by defeat at Celtic a fortnight ago.
"Yes, Russian teams have made it difficult for us in the past," said Vilanova. "These days you can't beat anyone easily in the Champions League.
"Against Spartak we'll try to win so that we can qualify but if we don't win we still have a game at the Camp Nou."
