George Burley is looking for Mario Licka to take confidence from his winning goal against Stoke on Saturday.
Licka's superb solo effort snapped a three-game Southampton losing streak and drew praise from Burley.
"We got him on a free transfer from the Czech Republic and he is still settling in, but he scored a terrific goal," said Burley.
"He is always a threat with his midfield runs and I asked him at half time to get further forward.
"We got him in the summer and he got injured in our final pre-season match. He has been out for two months, but he is fit now and ready to prove what a good player he is.
"He is a player with terrific potential and hopefully scoring a goal like that will give him the confidence to express it."
Stoke manager Tony Pulis was left cursing his luck on the South Coast and wants his side to be more clinical in front of goal.
"It was a good performance, but I am disappointed with the result," said Pulis.
"We had enough chances to get on the scoresheet and we have to start being more clinical in the final third."
