The 24-year-old has fallen down the pecking order at Chelsea following the arrivals of Liam Delap and Joao Pedro earlier in the summer.
Jackson is subject to interest from several clubs in the Premier League and abroad, but Chelsea’s £60 million asking price has made any potential deal tricky.
According to TalkSPORT, Chelsea are willing to let the Senegal international leave loan this transfer window as long as they receive a £10 million loan fee.
German giants Bayern Munich are understood to have agreed personal terms with Jackson, but Chelsea are holding out on a sizeable payment as part of any loan deal.
The imminent arrival of Garnacho from Man United may force Chelsea’s hand, however, as they hope to free up some space.
