Former Juventus GM Luciano Moggi isn't surprised to see Barcelona struggling.

Juve visit Barca this week for the return-leg of their Champions League quarterfinal leading 3-0 on aggregate.

Moggi pondered with AS: "Do you want to know what the real problem of Barcelona?

"They're without a coach. If a manager says 'at the end of this year I'm going', it's like I'm gone. The team is unmotivated, without ideas, without strength. And on the field, it shows.

"The midfield did not support either the offensive trident or the defence, which this year does not work at all well."
