The Irishman was signed as a 17-year-old by the Waterford Bohemians in 1999 and scored 393 appearances for United, winning five Premier League titles.
He was not flash but O’Shea was versatile and reliable and absolutely loved what Sir Alex Ferguson brought to the table.
But since he signed with United in 2006, O’Shea’s long-time teammate Carrick felt he didn’t get the credit he deserved.
“Sheezy was a great boy but he didn’t get the respect he deserved outside of the United States except Ireland, where he was a legend,” Carrick wrote in his 2018 autobiography. Between Lines.
“That year, Sheesy played right-back every game and he was amazing.
“Midfield, left back or center back, Cheesy plays anywhere for the team. He understood what it meant to play for United, what it takes to win and how to act.
“He was a model pro right off the pitch, and I see why Sir Alex kept Cheesy in the United for 12 years because he never had to worry about him, he never had to babysit him.
“The boss knew that Sheesy was ready when he needed it.”
O’Shea left Sunderland in 2011 after leaving United and then moved to Reading, where he is now the first team coach.
Carrick, meanwhile, won 2-0 against Villarreal in the first match of interim United boss Villarreal after sacking Ole Gunnar Soulszare.
As a result, United qualified for the Champions League knockout stages. Although he only takes responsibility for one match, O’Shea believes Carrick will do the job because he is “too quiet, too calculating and ultimately too focused on the team.”
