The Latics dropped their first group stage game on Thursday night, losing 1-0 at Rubin Kazan, but managed to remain second on the Group D table with two fixtures remaining.
In those matches, Wigan meet Zulte-Waregem at home and NK Maribor away with Coyle suggesting they have what it takes to join group leaders Rubin in the Round of 32.
"I think at the outset, everybody felt - and rightly so - that Rubin would be the favourites to win the group," Coyle said.
"But with what we have shown in the two games, home and away against Rubin, we are confident going into our last two group games.
"We have the quality to progress from the group.
"We have to keep putting in performances like tonight and if we do that it will see us earn enough points to qualify for the knockout stages.
"On another day it would have resulted in not even a draw but a win for us.
"There are a lot of positives and is a lot to be pleased about."
