That has been firmly established with James, who has endured a frustrating season with only five appearances so far. The Cobham graduate is only just returning to training after spending three months out with a knee problem, so there is some opportunity for Gusto to step in if James continues to be hampered by injury.
And for Potter, having two quality right-backs at his disposal will represent a positive dilemma for the 47-year-old, as opposed to the scenario of having no players available.
For Gusto, the challenge has been set for him to prove his worth with an elongated goodbye at his boyhood club before his big move to London in the summer. Because when pre-season starts in July, it will be down to him to prove he is able to compete with James for that starting spot, which is far from a straightforward task.
