He was appointed as manager of Bohemians in November 2006.[4] He led the "Bohs" to third-place in 2007, earning them a place in the UEFA Intertoto Cup. He also took the club to the semi-finals of the FAI Cup, where they were beaten by Cork City at Dalymount Park. However, he was sacked by the club after he allegedly made "advances of a sexual nature" to a female volunteer; Connor denied the claim.[5]
In December 2008, he was appointed as the manager of newly-promoted Premier Division side Dundalk, who were transitioning from amateur status to becoming professional.[6] He was voted Premier Division Manager of the Month for July 2009, and led the club to a fifth-place finish in the 2009 season, earning them a place in the following season's UEFA Europa League qualification rounds. He resigned in November 2009.[7]
In January 2010, he signed a three-year contract to manage Galway United. He led the "Tribesmen" to an eighth-place finish in the 2010 season, and a relegation play-off win over Bray Wanderers at Terryland Park secured the club a place in the top-flight for the following year. His contract was "terminated by mutual agreement" in September 2011 after the club suffered their 23rd consecutive league defeat.[8]
Africa
In January 2012, Connor was appointed as manager of Zimbabwe Premier Soccer League side CAPS United.[1] His contract was terminated in August 2012 following a poor run of results.[9] He fled Zimbabwe after claiming that he had received death threats from the club's staff and fans, that the club still owed him $90,000, and that the players deliberately underperformed to get him the sack.[9] He spent some time in exile in South Africa without finances as the legal battle with CAPS United continued.[10]
He signed a three-year contract to manage South African National First Division side Black Leopards in July 2014. He was instructed to guide the club into the Premier Soccer League.[11] He was fired after just six weeks having picked up just two points from his first three games.[12] He joined the coaching staff at the Maiden City Soccer Academy in County Londonderry in March 2015.[13]
Institute
On 14 September 2019, he returned to senior management when he was appointed as first-team manager at NIFL Premiership club Institute.[14] The "Sky Blues" were relegated after finishing bottom of the Premiership when the 2019–20 season was curtailed due to the COVID-19 pandemic in Northern Ireland; Connor said the decision to relegate the club without the full fixture list completed was "a very, very sad day for football".[15] The 2020–21 campaign did not take place due to the pandemic.[16] He was sacked on 17 August 2021, "following deep and personal discussions" after a poor start to the 2021–22 season which saw Institute lose their opening three NIFL Championship games.[17][18]
Return to Africa
He returned to South Africa as technical director at Cape Town Spurs on 3 October 2023.[19]
