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. This team looks a bit more physical and a bit more ready, more advanced physically than the opposition we had the other night."
On the Aussie fans, he added: "I must say tonight that 84,000 people… in two games we have over £160,000 people in Australia. It makes us realise how big the support is here in Australia, and how much people love football and sport here. It's absolutely amazing."
