Swansea City are all but assured of Premier League survival following their 1-0 victory over Chelsea, according to head coach Francesco Guidolin.
Gylfi Sigurdsson scored the only goal as the Welsh club claimed a maiden Premier League win against Chelsea, inflicting a first league defeat on Guus Hiddink since his December appointment.
The result moves Swansea onto 40 points, 13 clear of 18th-placed Sunderland, who have seven matches left to play.
"This is the first victory in the Premier League for Swansea against Chelsea and I am happy and proud," Guidolin is quoted as saying by BBC Sport.
"We played very well in the first half. We deserved to score other goals.
"It's a very important win for our fans. It's a good afternoon for our players, our club and our fans.
"Safety is almost real, but I hope to take other points in the next weeks because it's important to finish well."
Defender Angel Rangel added: "With the 40 points we're far away from the bottom and to beat Chelsea for the first time in the Premier League is a great achievement.
"All the players put a good shift in today and overall it was a great performance.
"With this win everything looks much easier now."
