The defender recently sat down with club media for a special interview ahead of the milestone, reflecting on some key memories from his time as a Red.
The 31-year-old joined us from Leicester City back in the summer of 2019, and has been an important member of our backline ever since.
In the exclusive chat with Harry, he reflected on his debut - a 4-0 triumph at home to Chelsea - and the pride he felt in walking out as a United player at Old Trafford for the first time.
"[I] signed not many days before the first game of the season, [and] obviously got put straight into the team," he recalled.
