The Tanzania international arrived from Genk this month for £8.5million to take over the spot vacated by the injured Wesley.
And Smith wants to see Samatta get his first goal against Leicester City in the Carabao Cup semi final tonight.
"We've all seen before how expectations can be built up, but not from within the building," said Smith to reporters.
"There's always an adaptation risk when a player comes in from another country, and we've had a few this season.
"We're not expecting him to hit the ground running straight away, but we know the qualities he has and hopefully he can bring them to the forefront straight away."
Smith added: "He's a different kind of player.
"Wesley's big, strong, can make the ball stick, he can link it up. Ally's more of a player that will work off the shoulders, a penalty-box goalscorer. They're different types of strikers."
