Wigan manager Roberto Martinez praised Victor Moses after he scored the winner against West Brom at the DW Stadium.
The 19-year-old stepped off the bench to help secure their first victory in six league games and take them out of the bottom three. Moses replaced the ineffective Jordi Gomez at half time and showed remarkable maturity in front of goal to seal a 1-0 victory.
"We wanted to stretch the game and that is why I sent on Moses. He has the ability and is in a great moment," he said.
Moses steered his effort beyond Scott Carson and into the corner after being set up by the impressive Charles N'Zogbia.
It was the former Crystal Palace midfielder's first league goal this season - he found the target in the Carling Cup victory against Hartlepool.
He added: "He came on against Liverpool on Wednesday and did well. I am not just using him as an impact player.
"He had a couple of injuries and has had to bide his time. He is still adapting to the Premier League. Victor is a very mature player and is ready to help the team. He is a raw talent."
Wigan went into the match having scored only nine goals in 12 league games but with renewed confidence after drawing with Liverpool.
Martinez said: "We knew it would be tricky. We have played three games in a week and the energy is not what it should be.
"They were organised and were playing for the counter-attack. We had to break them down and you allow the frustration to come out when that happens. Since the transfer window closed we have seen a new Charles. Physically and tactically he's taking his game to a different level."
