Its quite easy. We have the 9-10 highest revenue in Europe today. If you look at the next 5-10 years, we are probably going to have trouble getting much higher than that with the EPL generating a shit load of money, Bayern/ Real and Barca being far ahead in financial terms, and oilsheiks in Paris willing to invest, without sustainable business as a goal. That means we cant compete on wages and transfer fees, and ultimately that means that some players are not attainable to us.
10 years ago this club was almost bankrupt, and before the current management, the club was mismanaged for 4 years. For me it is pretty fucking impressive that we are able to compete with the best at this point in time and our management deserves the utmost respect for the way they are running the club.
