Chelsea have long been known for their huge spending ever since Roman Abramovich bought the club in 2004, and manager Jose Mourinho oversaw a £90m outlay as Atletico Madrid duo Filipe Luis and Diego Costa, Barcelona's Cesc Fabregas, QPR's Loic Remy and former Blues legend Didier Drogba all arrived in a bid to reclaim the Premier League title.
However, the recent transfer activity has been somewhat different from Chelsea, as they try to balance the books. January saw Juan Mata join Manchester United for £37m, whilst David Luiz joined Paris Saint-Germain for £40m and Romelu Lukaku was sold to Everton for £28m this summer.
With Financial Fair Play regulations now in place, Chelsea are required to monitor their spending, and manager Mourinho says that the club will continue to do so in the coming transfer windows.
"We are making money to be able to spend money. In every transfer window Chelsea is losing players, is selling players," he said. "So Chelsea in this moment is not a spender - Chelsea in this moment is making more money in transfers than the money we spend."
Whilst discussing the transfer plans of Chelsea, Mourinho turned his attention to Manchester United's recent spending spree. Louis van Gaal's men have forked out over £150m on new talent as Marcos Rojo, Luke Shaw, Daley Blind, Ander Herrera, Angel Di Maria and Radamel Falcao moved to Old Trafford. The Red Devils broke the English transfer record by paying £60m for Real Madrid star Di Maria, and Mourinho says that United have an unfair advantage when it comes to Financial Fair Play.
"When UEFA decided for financial fair play, they were trying to do this to make every team [have] equal possibilities, but the reality is that the big teams, the big clubs, the clubs with more years at the top with more fan base around the world, with more income, are the players that keep being the big spenders," he said. "So Real Madrid, Barcelona, Bayern, Manchester [United] - all these huge teams - I think they have an advantage."
