On-loan Manchester United forward Powell became the first Wigan player to score in the Europa League on Thursday night against Maribor before adding a second in a 3-1 success.
Coyle said of the 19 year old: "That's why we brought him here because I believe he's a top player in the making and nights like this will certainly help.
"He's got so much to offer. I want it on a consistent basis, and I'm trying to demand that of him to help him progress his career.
"I've been fortunate to be able to do that before with a couple of very good players and I see Nick Powell in that category.
"To do that he's got to bring performances like this on a consistent basis and show that after his year's loan, when he goes back to Manchester United, that he's in a position to challenge for their first team.
"And if he is, given the level they play at, that would then push him towards the England limelight. He's a bit off that yet but he's certainly got the ingredients that we can help to move him forward."
