The 17-year-old joined the Reds last year having played with Dungannon United Youth and Dungannon Swifts.
The Northern Ireland youth international - he captained his country’s U16s to success in the Victory Shield - officially signed in September 2019 after receiving international clearance.
A versatile and athletic player, Bradley has played most of his Liverpool games at right-back for the U18s, although he can also be deployed further forward.
His first goal arrived against West Bromwich Albion in November and he scored a superb effort versus Tottenham Hotspur on his FA Youth Cup debut in December.
