Hudson-Odoi joins Forest and three leave Chelsea on loan
Callum Hudson-Odoi has left Chelsea to join Nottingham Forest in a £5m deal.
The 22-year-old had been out of the first-team picture at Stamford Bridge for some time and spent last season on loan at Bayer Leverkusen.
Also on deadline day, Chelsea signed Cole Palmer from Manchester City.
Meanwhile, Diego Moreira moved to Lyon, Mason Murstow to Sunderland and Bashir Humphreys to Swansea on season-long loans.
Humphreys made his move after signing a new four-year contract with Chelsea.
