The media and fans around the world have been surprised by the strong stand and, as revealed by the Daily Mail, this is the attacker of the Blades McGoldrick who orchestrated the stand.
The player of 32 years, who played 25 minutes, had first proposed the idea to the captain-Sharp before the couple has a conversation with Heaton, the main figure of Villa.
The goalkeeper is currently sidelined until next season with the plan developed with the 34-year-old who relays the message to the team of Villa, Dean Smith and managing director Christian Purslow.
Speaking after the 0-0 first-leg draw, Smith said: “We knew that we were going to attract a public that is huge from the first game and that is something that we hold close to our heart.
“I have spoken of the participation of Tyrone to a protest march last week and he had my full support and my support. There is anyway no place for racism in our communities.
“Ourselves and Sheffield United have communities proud and we want to eliminate racism in any society.
“The players were talking and we decided that this was the way to go. Michael (Oliver) heard that we had something planned and asked him if he could check with the Premier League and we have said that it did not matter, we do it .
“It means a lot to many people and we wanted to pass on a strong message. “
