Fees in euros as reported by the data provider; estimates marked (est.). Loans and free transfers are counted as moves but not as money; an undisclosed fee counts as zero. A move between two clubs in this league appears under both — as a signing for one and a departure for the other. Contract extensions are excluded. Window dates are calendar-derived (summer = 1 June to 30 September).
