Kilkenny City He made his
League of Ireland debut for his local senior side at
Buckley Park on 15 March 1998, against Dundalk, at the age of 17, scoring two goals and giving Kilkenny City a 2–1 win.
Sunderland Reddy, as a striker, signed for
Sunderland from
Kilkenny City in 1999. He spent five years on Wearside; between 2001 and his departure in 2004, he was loaned out to
Swindon,
Hull,
Barnsley,
York, and twice to
Sheffield Wednesday. He made 18 appearances for Sunderland, scoring twice, and he scored a late equalizer against
Middlesbrough in the league. This was followed by several press reports linking him with a move to the newly promoted Premiership side
Sheffield United. It was
Leeds United and
Bristol City who made more of a forward approach for the player. Grimsby had also made the signing of striker
Isaiah Rankin in the hope of combining the pair in an attempt to make a second assault on promotion from League Two, but Michael still had a persistent hip injury. Reddy managed to play the odd game, and soon Slade's replacement as manager,
Graham Rodger, was dismissed by the club after a 'poor' start to the season. In turn, the club appointed
Alan Buckley as his successor. The new Grimsby boss stated that he wanted to keep Reddy, who had by now undergone hip surgery. With Reddy interested in leaving
Blundell Park, he subsequently ignored contract talks in favor of potential offers from
Bristol City.
Leyton Orient had made an unsuccessful approach to Reddy's services. ==Personal life==
