Wenger’s decision to withdraw the versatile 18-year-old attacker after 73 encouraging minutes drew stinging criticism from fans and appeared to be met with equal astonishment from club captain Robin van Persie.
But Oxlade-Chamberlain, signed from Southampton in the summer for a fee that could eventually rise to £15m, is confident the Frenchman has confidence in his abilities despite having his first Premier League start cut short.
“I was happy to first get a start,” said Oxlade-Chamberlain. “That is a positive for me to take away, having the boss’s trust. I’ve got to just make sure that I repay that with my performances and just working hard in training and when I’m on the pitch. I’ve got to make sure I keep my place now.”
