Chelsea are reportedly prepared to entertain offers for as many as 10 players during the summer transfer window.
With Kai Havertz potentially joining Hakim Ziyech and Timo Werner in moving to Stamford Bridge, Frank Lampard faces the prospect of taking his spending up to £150m.
According to Sky Sports News, Blues officials have informed the club legend that he must make player sales in order to make any further additions.
That has allegedly led to 10 players being made available, a list which includes goalkeeper Kepa Arrizabalaga and midfielder Jorginho.
Lampard is also prepared to sell at least one of Antonio Rudiger, Kurt Zouma and Andreas Christensen as he bids to make much-needed changes in defence.
Bids will also be considered for Emerson Palmieri, Victor Moses, Danny Drinkwater, Tiemoue Bakayoko and Michy Batshuayi.
