Arsenal have made £115.8million from selling academy players since the summer of 2015, with Alex Iwobi’s sale to Everton in the summer of 2019 the highest-earning.
The figure accounts for 31% of transfer monies received by the North London club, meaning that while much praise has been heaped on the club's academy for bringing through Emile Smith Rowe and Bukayo Saka it is also a strong source of income.
That is according to the latest post from CIES’ Football Observatory, which ranks the top 50 clubs worldwide to have "generated the most incomes since July 2015 from the transfer of players [who] graduated from their youth academy and having been at the club for at least three years between the seasons of their 15th and 21st birthday."
