Chelsea manager Jose Mourinho says that the contenders for the Premier League title are trying to buy silverware.
The current Premier League champions brought in Asmir Begovic and Falcao this summer for minimal fees and have not spent more than £30 million on one player since signing Fernando Torres from Liverpool back in 2011.
The Blues have still spent significant cash on the likes of Diego Costa, Cesc Fabregas, Eden Hazard and Nemanja Matic in recent years, but Mourinho claims that others are now trying to mirror the kind of spending that he enjoyed when he first took over the club in 2004 and lavished over £150m on players like Didier Drogba, Shaun Wright-Phillips, Arjen Robben and Petr Cech.
"In the beginning of Mr Abramovich coming to Chelsea, Chelsea was buying the title," Mourinho said after the friendly win over PSG on Saturday. "Now, they are buying the title. All of them, they are buying the title.
"It is up to us to be strong and to fight them and, obviously, to try and win it again, even without the big investments."
Manchester City spent £49m alone on bringing in Raheem Sterling this summer, while Manchester United and Liverpool have also spent large amounts of money on improving their squads ahead of the new season.
