Swansea City head coach Paul Clement believes his side's win over Stoke could provide the momentum they need to secure Premier League survival.
The Swans beat Stoke 2-0 on Saturday to end a six-match winless run.
Hull City's victory over Watford kept Swansea in the relegation zone, still two points adrift of the Tigers and safety.
But asked if momentum was back with his side after their triumph over Stoke, Clement said: "I think it is."
He added: "It's the first time I've called it a must win and I was right. If they [Hull] had won and we hadn't, the gap would have gone to five points with four games left.
