Chelsea are arguing with Bayer Leverkusen over their valuation of Kai Havertz.
Frank Lampard wants to sign the talented 21-year-old midfielder after completing a deal for RB Leipzig striker Timo Werner.
Bayer want at least £90m for the wunderkind, but the Express says the Blues think £75m is a fair price for the Germany international.
This could pave the way for Liverpool to swoop in, with Jurgen Klopp interested in recruiting Havertz as he looks to build a dynasty at Anfield.
Manchester United, Real Madrid and Barcelona are also monitoring the situation.
