Crystal Palace revived their hopes of securing Premier League survival with a 1-0 home defeat of Middlesbrough.
Victory, secured by a first-half goal from Patrick van Aanholt, also took them out of the bottom three and level with their visitors, who could yet struggle to avoid relegation.
Palace remain 17th but, having secured their first home league victory since Sam Allardyce's appointment in December, may yet have enough time to preserve their top-flight status.
Allardyce had had a fortnight uninterrupted by fixtures to work with his team, ending the demanding run that began with his arriva and finally giving him time to exert his influence during training.
