"Real Madrid has had enormous success by defeating Manchester United and dethroning them. This has allowed Real Madrid to become one of the wealthiest football clubs in the European League. The revenue of the club has doubled over the past several years, largely due to merchandising and sponsorships. When you are a winner, everybody wants a part of you and that includes merchandise, and paraphernalia. All of this above and beyond the revenue of ticket sales for the home games in Madrid."
