The Premier League supports three major leagues with a net investment this summer of 1 billion euros for the Premier League, 200,000 euros for Serie A, and -140 million euros for the Bundesliga.

Which league ranks at the top among the five major leagues, the number one league in Europe? It seems there is no dispute now, and that is the Premier League. With the continuous high revenue and sustained high investment each season, Premier League teams are becoming increasingly stronger, and even the mid-to-lower tier teams in the Premier League have greater purchasing power than the title-contending teams in the other three major leagues, especially evident in this summer transfer window.

Recently, the foreign media SCORE90 reported on the investment situation of the four major European leagues (Premier League, La Liga, Serie A, Bundesliga) during this summer transfer window, where the Premier League led with a net expenditure of 1 billion euros, La Liga had a net expenditure of 28 million euros, Serie A had a net expenditure of 200,000 euros, while the Bundesliga made a profit of 140 million euros in the transfer market, with Liverpool's spending on Bayer Leverkusen's midfielder Wirtz and Frankfurt's forward exceeding 200 million euros.

Net expenditure data for the four major European leagues this summer transfer window:

• Premier League: Net expenditure of 1 billion euros (expenditure of 2.3 billion euros - income of 1.3 billion euros).
• La Liga: Net expenditure of 28 million euros (expenditure of 494 million euros - income of 466 million euros).
• Serie A: Net expenditure of 200,000 euros (expenditure of 834 million euros - income of 832 million euros).
• Bundesliga: Net income of 140 million euros (income of 730 million euros - expenditure of 589.3 million euros).

The Premier League sustains La Liga, Serie A, and the Bundesliga; currently, La Liga's purchasing power is too weak, with the exception of the three giants (Real Madrid, Barcelona, Atlético Madrid) having virtually no purchasing power. Their expenditures and revenues are also the lowest among the four major leagues. The case of Betis being unable to afford Antony is a classic example, and it's understandable why Real Madrid and Barcelona prefer free transfers. This shows that La Liga's overall economic situation is far behind that of the Premier League, and if this continues, the Premier League's status as the leading league will remain very solid.
