At least it will benefit the club's income by changing the name of the stadium, not only ATMs do it, there are many clubs that change the name of their stadium for club income, the money that will be obtained can at least be used for club facilities and academy needs or buying players, but there is 1 club that is still strong and does not want to change the name of its stadium like Real Madrid, because we know that Real Madrid's money is very strong, so only clubs that have financial problems rent out their stadiums for club income.
Any club that needs potential investors can agree to that kind of deal. The money that was agreed in the deal that made Atletico signed the contract can be very useful and supportive to improve the team. These days not only football give the money use to manage a club but other investment, endorsement from gambling companies and gaming companies. So it is to their advantage that the Saudi Airline got into a deal with them. Meanwhile we all know how rich this Saudi investors can be. Its a huge opportunity for Atletico Madrid and they took it.

Are you really saying Atletico Madrid has some financial problem? Its a choice to make by the management but i don't think they have any financial problem of any sort. I believe that is their pattern of making money for the club. Real Madrid may not be in the business of accepting endorsement that will change their stadium name but i am certain they are in other businesses that yield them lots money.
