Blackpool boss Ian Holloway has challenged on-loan Wigan Athletic striker Nouha Dicko to prove himself a 90-minute performer.
All of the striker's three goals this season have come after being introduced off the bench.
Ollie said: "I need to work on teaching him how to get moving for 90 minutes.
"He wants to play 90 and I'm sure eventually he will. He's not a super-sub - he's a massive impact player."
