The 21-year-old will undergo a medical and, if there are no underlying issues, he will be confirmed as a Celtic player in the next couple of days.
The Belgian under-21 international will join Brendan Rodgers’ squad at Parkhead for an 18-month spell.
He was recently rewarded with a new five-year contract just last month. Celtic will pay a portion of his salary as well as a loan fee to Chelsea.
Musonda can operate on either wing or in the centre of midfield.
