Steve Clarke [SEP] Kilmarnock
After a year out of football, Clarke was appointed manager of Scottish Premiership club Kilmarnock on 14 October 2017. Kilmarnock was the club that Clarke had supported as a child. When he took over as manager, the club sat bottom of the league table. His first game as Kilmarnock manager, which was his first involvement in a Scottish club match for 30 years, ended in a 1–1 draw at Rangers. Three days later, Clarke's Kilmarnock side traveled to Celtic and once again gained a credible 1–1 draw. Following the league's winter break, Kilmarnock recorded a home victory over champions Celtic, with Youssouf Mulumbu scoring the only goal to inflict what was only the second domestic defeat on then Celtic manager Brendan Rodgers.
