Liverpool manager Jurgen Klopp has warned Chelsea that simply spending a lot of money in the transfer market will not guarantee success and much will depend on how quickly their new players "fit together".
Chelsea, owned by Russian billionaire Roman Abramovich, have spent around £200 million pounds (Dh957m) to bring in Timo Werner, Kai Havertz, Hakim Ziyech and Ben Chilwell, while Thiago Silva and Malang Sarr arrived on free transfers.
Premier League champions Liverpool, who finished 33 points ahead of Frank Lampard's side last season, have signed only left-back Konstantinos Tsimikas from Olympiakos Piraeus.
Klopp, who also guided Liverpool to Champions League and Fifa Club World Cup success over the past two seasons, believes hard work on the training ground is more important than heavy spending in the transfer market.
"We live in a world at the moment with a lot of uncertainty," Klopp told BBC. "For some clubs it's less important how uncertain the future is: those owned by countries, oligarchs, that's the truth. We're a different kind of club.
"We got to the Champions League final two years ago, we won it last year, and became Premier League champions last season by being the club we are.
"We cannot just change overnight and say, 'So now we want to behave like Chelsea'. They are signing a lot of players. That can be an advantage but that means they have to fit together pretty quickly.
"You cannot bring in the 11 best players and hope a week later they play the best football ever. It's about working together on the training ground."
Liverpool begin their title defence against newly-promoted Leeds United on Saturday while Chelsea face Brighton & Hove Albion on Monday.
