John Brayford praised United's medical team, after he scored the crucial second goal in Sunday's FA Cup quarter-final success over Charlton Athletic at Bramall Lane.
The Cardiff City loanee looked likely to miss United's biggest game of the season after injuring his calf at MK Dons earlier this month, but after working tirelessly throughout the week he declared himself fit and started against the Addicks.
Speaking after he remarked: "The physios deserve massive thanks. It's been hard work and frantic at times but they've been with me every single step of the way and I owe a lot to them.
"This time last week I was struggling to even climb the stairs at home, but there was absolutely no way I was going to miss out if I could help it.
"I owe the gaffer, the rest of the lads and this football club far too much for that, because they've been absolutely brilliant to me ever since I came in."
On reaching the last four of the most famous cup competition in the world, Brayford continued: "Incredible, brilliant, special, call it what you will. What we've just achieved is impossible to put into words.
"It's the stuff dreams are made of and just goes to show what you can do when you've got 11 warriors out there on that pitch who are just so proud to wear that red-and-white shirt.
"I just feel very, very proud to be a small part of what we've done. And now, we we'll be giving absolutely everything do go out at Wembley and try to do it all over again."
