Michael Theo

On 27 March 2018, it was announced that Theo's contract with the Roar would not be renewed after the 2017–18 A-League.

Prior to the 2014/15 season, Theo sustained a wrist injury in pre-season training which ruled him out for half of the season. Theo returned after the January Asian Cup break with a 3–2 home win against the Wellington Phoenix, despite conceding a foolish goal which was credited to Kenny Cunningham. Theo went on to play 3 more matches that season, keeping a clean sheet against the Central Coast Mariners, before injuring his quad muscle.

Following the 3–0 loss to Melbourne Victory, Theoklitos had gone 876 minutes without conceding a goal, setting a new record for the most minutes without conceding a goal in an Australian League—beating former recordholder Jeff Olver's record of 790 minutes. Theoklitos won the Goalkeeper of the Year award for the 2010/11 A-League season.

On 1 August 2012 Theoklitos announced that he had changed his name by deed poll to Michael Theo. He said: "Around the football traps, I’ve always been known as Michael Theo so I just thought, why not make it official? It’s no big deal, I haven’t changed my name completely, just shortened it. I’ve been thinking about it for a while and it was a decision I made on my own, it’s really not so hard to do on deed poll. My signature has altered, slightly changed but that’s pretty much it."

Theoklitos married Victoria Curtis in April 2011. She owns a cosmetics company.

On 14 March 2010, Theoklitos signed with the Brisbane Roar on a three-year deal. He made his debut in round one of the A league season against Gold Coast United, in a 0–0 draw. Theoklitos registered a second clean sheet against Sydney FC in round two.

The Michael Theo Soccer Academy was established in 2010, running annual clinics during the July school holiday period.

In the 2008/09 season, Theoklitos was part of Melbourne Victory's grand-final success, keeping five clean sheets at the end of the season. He earned another call-up to the Australian national squad for the match against Kuwait on 5 March 2009, but did not play.

In May 2009, Theoklitos declined a contract extension. In July 2009, it was confirmed that he would be leaving Melbourne Victory, with his contract expiring on 30 July. In early July 2009, he signed a two-year contract with English League One side Norwich City.

In the opening match of the season on 8 August 2009, Theoklitos made his debut for Norwich against Colchester United at Carrow Road, conceding five goals before half-time and seven in total. He described the match as "the worst performance I've had in my career" to BBC Radio Norfolk. Despite the performance, Theoklitos still had the support of manager Bryan Gunn, a former goalkeeper himself. However, Gunn did not have the support of the Norwich board, and was replaced by Colchester manager Paul Lambert, who had engineered the 7–1 defeat. Under Lambert, Theoklitos was demoted to third-choice goalkeeper.

Lambert confirmed in December 2009 that he expected Theoklitos to be leaving the club. Theoklitos' contract was terminated by mutual consent in March 2010. His debut was the only game he played for the Canaries.

He joined Melbourne Victory FC for their inaugural season in the 2005/06 A-League. In the 2006/07 A-League season, Theoklitos kept ten clean sheets from 21 games, attracting interest from both the Australia and Greece national associations. He has not made a senior appearance for either country.

Theoklitos began his career as a youngster playing in the Victorian Premier League (VPL) for Bulleen Zebras. He was then picked up by South Melbourne FC but failed to make an appearance. The Football Kingz FC showed a lot in interest in him, signing him for the 2001–2002 season where he became a fan favourite making 20 appearances in the National Soccer League. During his time with the Kingz he was scouted by Blackpool FC who signed him in 2002. Due to injury he only played in three games, only two of which counted as full representation for Blackpool. He returned to Australia where he rejoined Bulleen. While playing for them in the 2004 VPL final, he saved three of four penalties to help Bulleen to victory.

Michael Theo (formerly Theoklitos) (born 11 February 1981) is an Australian goalkeeper who most recently played for Brisbane Roar.
