Chelsea are planning to offload six players including Emerson Palmieri to fund a double raid for Kai Havertz and Ben Chilwell, according to a report.
Having been unable to spend last summer and failing to get any immediate deals over the line in January, Chelsea have emerged as the side to watch this summer.
Indeed, several reports earlier this month said Chelsea have agreed a deal worth around £50million to sign Timo Werner.
However, Chelsea owner Roman Abramovich reportedly wants two marquee signings in at Stamford Bridge.
As well as RB Leipzig striker Werner, Leicester left-back Chilwell and Bayer Leverkusen star Kai Havertz have been linked.
Both are reportedly worth over £70million and The Sun claims that Lampard will order a clear-out to fund the moves.
Top of the list will be midfielder Tiemoue Bakayoko, whose loan with Monaco is his second successive spell away.
Monaco are unlikely to take up the £35million purchase option in his current deal, meaning AC Milan – who signed him last season – could move in.
Emerson Palmieri could also go; Inter Milan and Juventus are both keen on the full-back, who wants to return to the Italian top flight.
The Sun says Chelsea hope both clubs will enter a bidding war for the former Roma left-back.
NOT ALL PLAIN SAILING FOR CHELSEA?
Danny Drinkwater and Davide Zappacosta will also leave, but Chelsea will struggle to generate a sufficient return on the pair.
Drinkwater has rarely featured in spells with Burnley and Aston Villa, having signed from Leicester for £35million in 2017.
Zappacosta, who signed for £25million in the same transfer window, has not yet recovered from a serious injury suffered on a loan spell at Roma.
Finally, Lampard is unlikely to block Victor Moses’ exit and the 29-year-old could leave after going to Inter on loan.
