Walker-Peters could be forgiven for having being a touch nervous prior to kickoff, considering that he was up against in-form Raheem Sterling on the.
Despite a few hairy moments, the 22-year-old came through the test relatively well.
And although Pochettino concedes that the Tottenham product had an okay evening, he says that he is unproven as the North Londoners' first-choice option for that role.
