Manchester City fullback Pablo Zabaleta can't put his finger on their problems in the Champions League.
With City boasting plenty of world-class talent of their own, Zabaleta is puzzled as to why they have failed to win any of their first five Group D games.
The Argentina international said: "We are obviously a bit disappointed about the result as we needed three points.
"It was our last chance to get close enough to Real Madrid and Borussia Dortmund, and play the last game with an option to go through to the next stage.
"Now, the chance has gone and it's hard to understand.
"It's the second year in a row that this has happened - it's hard to see, when you see the players that we have.
"The group was very tough. Borussia Dortmund did very well and maybe Real Madrid were the second best team in the group and that's why we didn't qualify for the next round."
