Scott will co-present alongside Dermot O’Leary as the touchline correspondent for the live charity event.
"Soccer Aid 2021 for UNICEF is going to be just brilliant," said Scott. "It's great to be involved again, and of course co-presenting alongside Dermot is really exciting.
"It'll be so special to be back in a stadium with fans again, and all for a great cause. Tickets are on sale now – see you in September!"
