Actually I'd be surprised if the revenue isn't a minimum of €14m. Even if you add only 10,000 extra fans per home game (taking us up to around 33,000 per game) if you sold those tickets for a mere €10 you are talking €19m. And that's a low estimated ticket cost. Sure, turnout could be less but tickets will be more, and that doesn't take into account corporate sales, which seem to figure heavily in this stadium.
