Mackie came through the system at Wimbledon.
"I'd always say I was a former Wimbledon player," Mackie told the Daily Mail. "I just don’t feel as emotionally attached to the MK Dons. Wimbledon was my first club.
"I made my debut in the league for the club, even though, strangely, it was playing in Milton Keynes.
"But the badge said Wimbledon. We were Wimbledon, we had Wimbledon’s history — we just weren’t playing there."
