The BBC's File on 4 programme has been investigating online racism within football to try to find out why such abuse was sent to England's players after the Euro 2020 final.
The programme approached a number of these trolls, and one man who racially abused Bukayo Saka online says he now wants to apologise.
Saka, Marcus Rashford and Jadon Sancho all received a torrent of racist abuse online after missing penalties in the final.
One troll - a man in his early twenties from Saudi Arabia - sent Saka a number of monkey emojis on Instagram.
