Juventus president Andrea Agnelli admits Italy's financial crisis has hurt the football industry.

Allegri was speaking in Dubai at the Globe Soccer Forum.

"Chelsea sell their tickets for double the price of Juventus, while in Germany the average wage is much higher than in Italy, so it's not just an issue of stadiums. Nonetheless, we must try to relaunch where we can.

"Roma are about to take an important step by building their own stadium and more should follow suit."
