Juventus GM Beppe Marotta says Italian clubs will lag behind their German counterparts so long as local stadiums remain a problem.

Juve were dumped out of the Champions League by Bayern Munich last night.

Marotta said: "It is very simple, as Italian sides have almost 70% of their revenue from TV rights, whereas the German clubs split between TV rights, commercial rights and the stadiums. It's clear in Italy that there is a lack of stadiums that can be owned by the clubs to boost income.

"I thank our squad, as we started this new era two and a half years ago, when we never imagined we'd be in the Champions League quarter-finals against a huge superpower like Bayern.

"We are still working and do not have the quality needed as yet to be in that group of superpowers. Unfortunately, right now the Italian clubs are far behind in purely economic terms, which therefore affects the transfer potential."
