That was the highlight of Saints' 29-17 win over the Welsh Region that keeps them in hunt to win Pool 1 and possibly qualify for a Heineken Cup or Amlin Challenge Cup place. To do that they will have to beat the French champions Castres Olympique at Franklin's Gardens this weekend.
The likelihood is that North's side will have to score four tries to grab a bonus point, and the Ospreys will have to beat current Pool leaders in Dublin. It is a tough ask, but anything can happen in the Heineken Cup!
"From our point of view, we've got one game left and we are going to go flat out and try to get five points," said North, who scored in front of the on-looking Wales coach Warren Gatland.
"It has been a tough group for us to get back into after a couple of early losses, and it is now win or nothing for us against Castres. We've still got a chance of making it, and we will go hard until the end.
"The first-half was quite frustrating today. It was quite a slow game, and we needed to bump the pace up to how we wanted to play. I had a bit of space and time for the try, so it was happy days."
Northampton rugby director Jim Mallinder believes the Wales and British & Irish Lions wing is settling into the patterns at his new club and paid tribute to his game-breaking ability
"It was a quality try by George. He is really settling in to the way we want to play. People say he had a slow start with us, but he did some brilliant things early on in the season," said Mallinder.
"He's a quality player. I know he is young, but he is determined to improve and work hard at his game, which is what he's doing. He is playing for a good club, he's playing for Wales and he is happy."
