For the better part of 13 years, Andrew Redmayne was asking himself whether he was good enough to play for Arsenal. On Thursday night, he found out that he apparently was.

After putting in a man-of-the-match display against the club he spent weeks on trial with as a teenager, Arsenal coach Arsene Wenger admits the club made a mistake in not signing Redmayne when they had the chance.

"I would say the goalkeeper was man of the match," Wenger said. "I don't remember [if he trialled with Arsenal], I have to say it's such a long time ago. But, if he was with us, we made a mistake."

Redmayne appeared a man possessed, pulling-off a string of fine saves including denying England international Danny Welbeck from the spot in Sydney's 2-0 loss to Arsenal to make a major road to cementing a first team spot for the Sky Blues and reminding the Gunners on what they missed out on.
