The estimated €4.6bn (£4bn) spend by Premier League clubs this summer is larger than that of the next eight largest European countries combined, raising concerns about the increasing concentration of talent and growing polarisation of the market. English clubs were involved in more than 60% of the deals and paid an average of around €24m (£20.7m) per inbound player, compared with only around €4m (£3.4m) to €5m (£4.3m) in the other major European leagues.
According to Uefa's executive director of finance, Andrea Traverso, transfer values continue to rise sharply, particularly in the English market, increasing future pressure on club financial results. Traverso also warned that any "correction in transfer values" or "slowdown in buyer demand" could have serious implications for any club carrying debt.
