Mendy was an unused substitute during Gambia's 3-2 loss to Burundi, but Parkinson hopes that he will get some minutes in the next match against Ivory Coast on Sunday to prove his mettle on the international stage.
"The Gambian manager has been monitoring him, closely," Parkinson said. "There's other players in his position and he's got competition as you'd expect. But he's done well to get in there. Obviously, he wants to have some minutes to show what he can do. I'd like to see him get some game time and not have a trip where he goes there and is just a squad player. Obviously we've got a lot of belief in Jacob and we think he's a really good player."
