Chelsea planned to offload 11 players after agreeing to Timo Werner in the summer transfer window.
The Blues set to wrapping up their £53million capture of the 24-year-old RB Leipzig Germany striker who has scored 25 goals in the Bundesliga this season, will sign a five-year deal worth £200,000 a week.
Chelsea who have Leicester ’s Ben Chilwell in their sights, could also now move for 23-year-old Sassuolo forward Jeremie Boga, who spent nine years at Stamford Bridge before joining his current club two years ago.
The Europa League holders have a buy-back clause for the versatile star who has eight goals and assisting another four in 24 league appearances this season.
Lampard has already splashed out £38million for Ajax winger Hakim Ziyech earlier in the year.
The club are already set to get Spanish winger Pedro off the wage bill on a free transfer with Roma believed to be in pole position for his services, while Brazil international 32-year-old Willian, 32 in August, is also set to part company with the club after failing to agree a new contract.
The Mirror reveal that Chelsea will also let Jorginho reunite his former boss Maurizio Sarri at Juventus, while Lampard will also sell left-back Marcos Alonso who is wanted by another ex-Chelsea manager, Antonio Conte at Inter Milan.
However, West Ham boss David Moyes is keen to be reunited with former Everton midfielder Ross Barkley, who has failed to nail down a regular starting place under Lampard but the arrival of Werner, who has scored 25 goals in the Bundesliga this season, means the end of the line for Michy Batshuayi.
Chelsea will also cash in on several players who have spent the season out on loan with defensive midfielder Tiemoue Bakayoko should be sold to suitors Paris Saint-Germain once he returns from his Monaco loan and Davide Zappacosta could make his Roma loan permanent despite penning a new contract last summer.
The Blues will bank £48m for Alvaro Morata when the striker’s loan at Atletico Madrid becomes permanent on July 1.
