Chelsea are reportedly in discussions with AC Milan to sell midfielder Tiemoue Bakayoko.
According to Sky in Italy, Milan are keen to bring the France international back to the San Siro, after the 25-year-old's previous loan spell in 2018/19.
Bakayoko joined Chelsea from Monaco in a deal worth £40m in 2017, but has failed to live up to expectations and is thought to be surplus to requirements at Stamford Bridge.
The midfielder was loaned out to Monaco last season, and looks set to be sold this summer to raise funds for Blues boss Frank Lampard's transfer targets.
According to the report, Chelsea could demand a €3million (£2.7m) loan fee for Bakayoko, with an option inserted to buy the midfielder permanently for €35million (£31.5m).
Having already sealed deals for striker Timo Werner and Hakim Ziyech, the Blues could use the cash injection from Bakayoko's departure to help fund moves for Bayer Leverkusen midfielder Kai Havertz, with the Germany international thought to be Chelsea's priority signing.
The Blues are thought to have agreed personal terms with the 21-year-old, but must still agree a fee with Leverkusen, with the Bundesliga side reportedly holding out for closer to £90million.
Another position Lampard is keen to strengthen is at left-back, with Leicester City's Ben Chilwell among the club's main targets.
Real Madrid's Sergio Reguilon and Atalanta's Robin Gosens are also reportedly on the Blues' radar.
Speaking after Chelsea's Champions League exit to Bayern Munich at the weekend, Lampard was asked if there will be more arrivals at Stamford Bridge.
"We'll look at that, because that's our job, we're very joined up on that already," he told BT Sport.
"From having a transfer ban (last summer) you feel we've missed where other clubs have spent and improved, and recruitment is a huge part of this game.
"Nights like this in a footballing sense, show me a lot, tell me a lot.
"So it's a conversation now, the season is ended, it's a very quick turnaround, so now is the time to see where we can improve, what areas we can improve on."
