Tottenham ready for acid test at Arsenal: Postecoglou

Postecoglou's unbeaten team sit second in the Premier League, two places above Arsenal, after winning four of their first five games.
Tottenham's campaign opened with low expectations following Harry Kane's move to Bayern Munich and concerns that former Celtic manager Postecoglou would struggle to adapt to the Premier League.
But the Australian has defied those fears so far, producing a free-scoring team, with 13 goals in five league games, that serves as a welcome tonic to the dour reign of predecessor Antonio Conte.
A first league victory at Arsenal since 2010 would serve as another significant milestone in Tottenham's development under Postecoglou.
"From our perspective, it's a great challenge for us as a football team that's beginning on a journey and trying to have an identity on the way we play. There's no greater test than playing one of the top teams in the country away from home, who also happens to be your biggest rival," he said on Friday.
Arsenal are among the leading title contenders after coming close to taking the trophy from Manchester City last term and making an unbeaten start to the current campaign.
While Postecoglou is well aware of the message a win against Arsenal would send to the rest of the league, he is keen to focus on the quality of the performance, rather than solely on the result.

"We're five games in. I understand that for many people, they will see this as our first real test and I get that. For me, what is going to be more important is how much of our football I see in a big game like this. How much of us can I see against a top opponent?," he said.
"That will give me the biggest indicator of where we're at, but ultimately we'll still be six games into a new cycle, a new group of players, a very young group of players."
Similarities can be drawn between the rebuilding job Postecoglou has been tasked with at Tottenham and the work achieved by Mikel Arteta during the past four years at Arsenal.
"They have a new challenge, a new opportunity. They have a new manager who is doing really well and he's managed to change the vibe around the club, with a different style too," Arteta said.
"I really like him. I have players who had him before and they always speak really highly of him, which is not a coincidence because straight away he's fitting in the right way.
"We need to be ourselves and produce the performance to beat them. That's the beauty of the league where there are top managers, competition and every game is very difficult."
