Newcastle United manager Rafa Benitez has admitted the confidence boosting win over Southampton could keep them in the Premier League.

The Magpies strolled to a 3-0 victory over fellow relegation strugglers, Southampton, on Saturday. The win propelled Newcastle up to 13th place on the table and five points out from the drop zone.

And Benitez insists confidence is running high at St. James' Park.

"When I do my maths, I don't waste too much time thinking this one is a must win," said Benitez.

"This was a fantastic game to win but the main thing is, if you are not strong enough to win, that you are strong enough to draw.

"These games are ones you cannot lose. If you draw you both get a point but they remain where they are as well.

"To win, is great; we were strong enough to control the game, now it is to the next game and we have to be strong for that one as well.

"The one thing we have is confidence in our team. We work really hard and we are doing well."
