Sutton United boss Paul Doswell has revealed Arsenal are donating £50,000 to the club.
FA Cup rules had meant Arsenal were unable to donate their share of the £100,00-plus gate receipts, but Doswell revealed Arsene Wenger's side had found a way to help their fellow Londoners, who they beat 2-0 with goals from Lucas Perez and Theo Walcott.
"The reality is that Arsenal have been superb all the way through this," Doswell told the London Evening Standard. "We think they're going to help us with the classroom, that's what we're trying.
"It's going to go into the community fund and they've promised us £50,000 and that will buy two classrooms.
"That is an amazing gesture from them and one we're very thankful for."
