English Premier League clubs spent a record £630 million ($1.25b) this summer to eclipse past transfer windows' expenditure by a significant margin.
This is also £140m higher than last season's figure.
When Liverpool signed French defender Mamadou Sakho for a fee of £18m early on Monday, they already helped to smash the league's previous high of £500m, which was recorded in 2008.
Although Spanish La Liga side Real Madrid made sure some of that cash flowed back into England with their £86m purchase of Tottenham Hotspur's Gareth Bale, it didn't even come close to matching the Premiership's net spending.
According to financial analysts Deloitte, a total of £400m - another record - left the league during this period.
By splashing out £109.3m ($217m) on new players, Tottenham are the top spenders in the EPL in the transfer window.
Well, at least they recovered £86m from the sale of Bale to Real. In the eyes of many, Spurs had done shrewd business in capturing quality players such as Erik Lamela, Christian Eriksen, Paulinho and Roberto Soldado.
Like the Lilywhites, Man City, second on the chart on £92m, made their moves early, too. Stevan Jovetic, Fernandinho, Jesus Navas and Alvaro Negredo were all snapped up before the mad rush on deadline day.
Chelsea, Liverpool and Arsenal occupy the next three spots on the list.
