Frank Lampard's X-rated touchline row with Jurgen Klopp and his Liverpool staff at the end of last season appeared to be a rare feud that spiralled out of control very quickly.
But despite the Lampard's subsequent regret over the incident, it appears his German counterpart has reignited the fire between them after turning the spotlight on Chelsea for their spending in this season's transfer market.
The Blues have splashed £230m this summer on shiny new signings including German duo Kai Havertz and Timo Werner, leading Klopp to say: 'For some clubs it seems less important how uncertain the future is.

But was the German right to complain about Frank Lampard and Chelsea splashing the cash?
Alisson - £67m
Trent Alexander-Arnold - Academy
Joe Gomez - £6m
Virgil Van Dijk - £75m
Andy Robertson - £8m
Naby Keita - £57m
Jordan Henderson - £20m

Mo Salah - £39m
Roberto Firmino - £29m

'Owned by countries, owned by oligarchs, that's the truth. We are 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, by being led the way we are led.
'We cannot just change it overnight and say, "So now we want to behave like Chelsea, now they've signed a lot of players".'
Lampard has since hit back claiming Chelsea have only followed in Liverpool's footsteps this summer, with the Reds having forked out huge sums of cash on the likes of Virgil van Dijk, Alisson and Fabinho in recent seasons.
But does Klopp have a point, especially during the current financial slump, or will he be made to eat his own words?
Klopp claimed he was 'calm' despite being left behind by Chelsea and Manchester City in this season's market, with the champions having only added left-back Kostas Tsimikas to their squad.
But as interpreted by MailOnline's body language expert Judi James, Klopp showed signs of suppressed aggression, anger and defensiveness during the BBC interview.
Moreover, his comments also appear somewhat questionable given the cost of his XI against Leeds in comparison to Chelsea's likely XI against Brighton, with the wider picture giving Klopp no hint of vindication for his ire.

Alisson, a £67m signing from Roma, also played the seven-goal thriller at Anfield on Saturday
The starting line-up Klopp put out for Liverpool's win in the seven-goal thriller at Anfield on Saturday cost a whopping £356m.
Van Dijk was the most expensive player in the side following his £75m move from Southampton in January 2018, while £67m Alisson and £57m Naby Keita also started.
Liverpool's well-renowned attacking trio of Sadio Mane, Mo Salah and Roberto Firmino cost the club £98m in total, with Trent Alexander-Arnold the only academy product in Klopp's XI.
Scotland left-back Andy Robertson, England centre-back Joe Gomez and captain Jordan Henderson have been proven bargains with the club's Champions League and Premier League trophies during the last two seasons.
Naby Keita, a £57m signing from RB Leipzig, was also part of the Liverpool midfield
Kai Havertz, who joined Chelsea for £89m, is likely to be given the nod against
