Wigan striker Dicko starring at Blackpool
Dicko struck again in the draw with Crystal Palace on the weekend.
The scorer removed his top and ran 80 yards after scoring. His celebrations earned Dicko a booking but his boss didn't seem too concerned.
Appleton added: "I was joking with Nouha that I've never seen him move so quickly. Maybe he's quicker than I thought.
"He's making a habit of getting vital goals now. Two weeks running he's made, got himself into a good position in the box and scored. Nouha took his goal really well and looked delighted with it."
