"It's a difficult pace they play at. They're pretty much guns blazing for the whole 90 minutes," he told au.fourfourtwo.com.

The former Newcastle Jet, who left the A-League side last January, has been deployed as a right back at United and it's a position the Socceroo says he feels comfortable playing.

Two games into the K-League season and North's club Incheon United are unbeaten with one win and a draw. They sit in sixth spot, although most sides have played three games.

"They love their running, the physical side of the game but I've adapted well to it. And I've played a few games now," North added.

Although the 27-year-old is less comfortable with the language even if he feels settled in South Korea's third biggest city.

"It's a very difficult language but I'm learning the culture and settling in," he said."The most difficult part is communication. You can't yell man coming because they have their words for it. It's always difficult.

"I'm glad I'm in a big city [Incheon]. If I wasn't in a big city I'd be struggling and there are some K-League teams out in the country areas."

North, with 23 appearances for the green and gold, was an unused substitute for the Socceroos on Wednesday night as they secured their fifth win of this the final phase of World Cup qualifiers.

The Taree-born North describes the Socceroos' first half performance as being in a comfort zone.

"We let them play a little bit and we got into a little bit of a comfort zone and that's when Pim's [coach Pim Verbeek] come in and he's been fantastic throughout the campaign." he added.

"He's an experienced coach and it was a different team in the second half. He just said 'let's just forget about the first half and let's get on with the second half'.

"And everyone could see we were a different team in the second half."
