A crowd of 83,221 supporters flocked to ANZ Stadium on Saturday night as Arsenal defeated Western Sydney Wanderers 3-1, only two days after knocking off Sydney FC 2-0 in front of more than 80,000 fans.

The crowds were Arsenal's two biggest ever in a pre-season match and left Wenger amazed by the club's worldwide support.

"I must say after two nights here, we had over 160,000 people at the games and I am just absolutely bewildered," Wenger said.

"It makes us realise how big the support is here in Australia, and how much people love football and sport here.

"The people here in Australia are wonderful, they are very respectful, very nice, they love the Premier League and overall Sydney is absolutely beautiful so it was a dream to stay here.

"I am a long time in the game and it was amazing."

Wenger complimented Wanderers for their performance, acknowledging their physicality in comparison to Thursday's opponents Sydney FC.

Wanderers have been in pre-season five weeks while Sydney only returned last week following their A-League double triumph and the friendly against Liverpool in late May.

"This team looks a bit more physical and a bit more ready, more advanced physically than the opposition we had the other night," Wenger said.

"I felt that we did very well in the first half against an opposition that made it physical for us.

"They left always something in, and they pushed us to go into the challenges.

"Overall the first half was very positive, we played at a good pace, very fluent, technically very good and with the right intensity.

"Our target was to maintain that as long as we could. We dropped a bit in the second half because most of the players have had five days’ training.

"It was quite amazing how well they did. When the other team came on we got an impulse again and dominated.

"Unfortunately we couldn’t score but we hit the post twice and created chances. It’s a bit similar to what we have seen against Sydney FC - they defend with heart."
