Frank Lampard has suggested that Chelsea's spending this summer was just following on from Liverpool's lead in the past, before the Reds became Premier League champions.
The Blues have been the most active side this summer with Hakim Ziyech, Timo Werner, Kai Havertz, Ben Chilwell and Thiago Silva having already joined.
Klopp, who clashed with Lampard at the end of last season, aimed a dig at Chelsea's spending, as well as Manchester City's owners, and the former England midfielder has now hit back.
"The reality is - other than maybe Leicester, which was an incredible story - most clubs that win the League in the modern day have recruited well and have recruited at quite a high level money-wise," the Chelsea boss said.
"You can go through the Liverpool players - [Virgil] Van Dijk, Alisson, Fabinho, [Naby] Keita, [Sadio] Mane, [Mohamed] Salah. Incredible players that came at a very high price. Liverpool have done it over a period of time.
"What we have done is come off the back of a ban and probably try to address the situation to help improve us. We know that Liverpool have spent at a high level.
"We know they have an incredible coach. We know they have incredible players. The really smart thing Liverpool have done is believe in their coach and believe in their system for a number of years. It's a great story but it's a story where they've spent money on players."

Lampard was praised last season for coming into the club after just one year's experience as a manager, with Championship side Derby County, whilst the club had a transfer ban, before leading them to fourth place in the league and the FA Cup final.
The club's ban was actually reduced so they could have made signings in January but instead they stuck with the players they had, many who came from the academy.
Klopp has only added £11.75 million left back Kostas Tsimikas to the squad that won the Premier League at a canter last season.
The Reds have been heavily linked with a move for Bayern Munich midfielder Thiago but have reportedly refused to meet his €30 million transfer value up to now.
