The Bournemouth front man struck up a close friendship with Bradley, who was terminally-ill, during his two-year spell at Sunderland.
However, the youngster sadly lost his battle at the end of last season and died in July.
And despite leaving the Stadium of Light following their relegation to the Championship, Defoe clearly hasn’t forgotten about Bradley.
The 35-year-old appeared in the following video, published by Sunderland’s Twitter account, in which Defoe asks for the general public to follow him and help raise funds to build a holiday home for sick children, in Bradley’s memory:
A special message for his best mate…

Sunderland aim to raise money for the project through the sale of a special edition Adidas home shirt, affectionately named ‘Bradley’s Shirt’.
Bradley’s mum, Gemma Lowery, explained, “Bradley Lowery was an inspirational little boy who made a big impact on this club and the wider footballing world.
“We want to create a legacy for Bradley that will be for the good of everyone,” she added.
“Bradley’s Shirt will go a long way to making that happen, with all money made from sales of the special edition shirt helping to build memories for sick children and their extended families.”
Here’s hoping with Jermain’s backing they manage to reach their target!
