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.
"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.
