Arriving from six-time Premier League winners Chelsea, the highly sought after 20-year-old will spend the duration of the 2023-24 campaign at the Stadium of Light.
Burstow made his Premier League debut for the Blues earlier this month, featuring against West Ham United and then Luton Town before starting in a Carabao Cup victory over AFC Wimbledon.
The striker progressed through the ranks at Welling United and Maidstone United prior to joining Charlton Athletic and breaking into the Addicks’ senior team in 2021, aged 17.
Burstow moved to Stamford Bridge in February 2022 and immediately returned to The Valley on loan, ending the 2021-22 season with six goals and three assists in 23 first-team appearances.
