The defeat was the Championship clubs first in four European outings and was not completely deserved according to the manager who felt his Latics could have at least gained a pointy from the contest.
"I was a little bit annoyed in that from our point of view, it was a soft goal to lose," Coyle said.
"But in the second half, we dominated a very good side.
"We certainly shouldn't be leaving here on the end of a 1-0 scoreline. We have hit the woodwork and had numerous chances in the second half.
"In our first foray in European football, I think this was an outstanding performance - we looked like a very mature European team and I was delighted with them.
"My only disappointment is to leave with no points, because we certainly deserved to take something from the game."
Coyle added: "I felt the players were a credit to the football club.
"The fans travelled here to Kazan, who have made everyone feel very welcome, and I felt the players certainly showed application and a lot of quality at times as well on a difficult pitch.
"We are disappointed, but not with the performance - only in terms that we have taken no points and lost our uneaten record in European football."
