Sebastian Larsson believes Sunderland will boost its Premier League survival hopes with victory over Chelsea on Saturday.
Relegation-threatened Sunderland continues its latest attempt at staging a great escape this weekend when Chelsea travels to the Stadium of Light.
Sam Allardyce's side slipped into the bottom three last weekend after Newcastle United's win against Crystal Palace, Sunderland having snatched a late draw at Stoke City.
One point separates the two fierce rivals, although Sunderland has a game in hand on Rafael Benitez's side.
And they may well need it given their disappointing record against Chelsea, the visitors having won nine of their last 11 visits to Wearside – a run that stretches back nearly 16 years.
