Manuel Pellegrini felt Manchester City deserved at least a draw at Juventus and can still finish top of their Champions League Group D.
Mario Mandzukic scored the only goal in Turin, but both sides spurned a host of other chances. Raheem Sterling, Yaya Toure and Fernandinho all missed good opportunities for City, while Fernando had a header touched onto the post.
Pellegrini said: “It’s a difficult moment for the team. That’s why in this moment I am not so unhappy in the way we played because we didn’t have many chances to make substitutions.
“I think we were very unlucky to lose this game – I think the minimum we deserved was a draw.
“It’s not an easy stadium, it’s not an easy team, but we couldn’t get the result we wanted.”
Pellegrini has not given up hope of reclaiming top spot, but his side must beat Borussia Monchengladbach and hope Juventus lose at Sevilla.
“I think the group is not finished,” he said.
Juve boss Massimiliano Allegri is also taking nothing for granted in terms of the group, even though his side have guaranteed progress and now have a two-point advantage over City.
He said: “Mr Pellegrini is right. There is still one match left. If we lose and they win they will go ahead.
“We have to be focused on the Italian championship now but then get ready for the game against Sevilla.”
The Italians were impressive on the night and Paulo Dybala twice went close to doubling the lead, being denied by Hart and a post.
Allegri said: “I think this was a match of several chances for both sides. This has been a great Champions League match with some very good play.
“We played extremely well to get this result.”
