Russell Slade has called on his Leyton Orient side to impress him in training as they prepare for a busy October.
The O's will play eight times during this month, and Slade hopes some of his fringe players will provide him with selection headaches for the congested period.
"The more players I have available for this month the better, the more headaches I have when selecting my team the better - that's the way I see it," Slade told the club's official website.
"If players are showing up in training and doing well, you can rest one and put one in, really.
"That's the sort of problem I want this month rather than the XI picking itself."
