to 2018. Having gone through 2014–15 without scoring, he produced two goals in nine days in August 2015, contributing to his nomination for the Championship Player of the Month. The first came just before half-time at home to Derby County when his shot was deflected past the goalkeeper by a defender. For the second, away to his former club MK Dons, he curled Clayton Donaldson's cutback over the goalkeeper into the corner of the net; later in the match, he was stretchered off with an ankle injury that proved less serious than initially feared. He continued as first choice in a two-man midfield, generally partnering new signing Maikel Kieftenbeld, and according to the Birmingham Mail, was "arguably Blues' most important player, knitting together defence and attack and adding goals to his game". After an influential performance and a goal in a 5–2 win away to Fulham in November, Rowett sais he "[didn't] think there [was] a better passing defensive midfielder in the division." His celebration of a fortuitous goal in a 3–0 win at Derby earned him a booking for inciting the home supporters, and he apologised to the stewards after the match. Both his and the team's performances dipped towards the end of the season, which he finished with five goals from 46 appearances in all competitions. Gleeson was linked with moves to other Championship clubs, including Leeds United, Reading and Sheffield Wednesday, during the close season, and his pre-season was disrupted by an infected toe, but he still began the new campaign in the starting eleven. His selection as a starter was intermittent, dependent on injurieshis own or others'as well as on the sheer number of central midfielders available, especially after the creative Reece Brown returned to consideration. Playing a more advanced role in a 4–4–2 formation, Gleeson scored a winning goal against Blackburn Rovers in October, which preceded a run in the starting eleven, under both Rowett and his successor, Gianfranco Zola. As poor results continued, Zola introduced Tesche, whom he perceived as more capable defensively, and Gleeson started only one match in the last two months of the campaign. Ipswich Town Gleeson left Birmingham on a free transfer on 19 January 2018, and signed until the end of the season for another Championship club, Ipswich Town, under the management of Mick McCarthy who had given him his debut at Wolverhampton Wanderers. He made his first appearance
