West Bromwich Albion boss Roy Hodgson admitted some relief after victory over Blackburn Rovers.
A Martin Olsson own goal and second-half efforts from Marc-Antoine Fortune and Liam Ridgewell sealed victory.
Hodgson said: "It was a nervous occasion because after a bad March we've seen that security margin slip away.
"The Foster double save was the game changer. After a good start we started to play nervously and they played with great confidence.
"The 3-0 scoreline makes the game look more comfortable than it was."
