League of Ireland First Division, when offered the chance to sign for Limerick by his formed manager Martin Russell, Clarke jumped at the chance and was announced by the Superblues ahead of the 2015 season. With Limerick starting the season at Jackman Park while they waited for their new stadium to be completed and the poor facilities at Jackman proved to be something that the side badly struggled with as they sat at the bottom of the table come the halfway point of the season. Once they moved into the Markets Field, the team and Clarke's form skyrocketed and they produced incredible form to somehow get themselves off the foot of the table with Clarke bagging 6 goals in 32 games along the way but unfortunately they lost 2–1 on aggregate to First Division side Finn Harps in the Promotion/relegation playoff. Shamrock Rovers On 15 December 2015, Clarke returned to Dublin and signed for Shamrock Rovers. Rovers manager Pat Fenlon played Clarke as a support striker rather than his usual position on the wing. He played Clarke in 29 league games but the season was a disappointment to everyone at the club as they finished 22 points off Champions Dundalk in 4th place, were embarrassed in the FAI Cup, losing 5–0 at home to Cork City in the Quarter final and being knocked out of the UEFA Europa League in the first round, losing 3–1 on aggregate to RoPS of Finland, in Clarke's first two European appearances of his career. Return to Limerick With 2016 seeing Limerick promoted back to the Premier Division, Clarke was happy to return to Martin Russell's side and on 19 December 2016, he was announced as a Limerick player once again. With Limerick in bad form, Russell was sacked in April and replaced by Neil McDonald, who preferred to use Clarke as a winger and often as a full-back also at times. Clarke's only goal of the season came in a 5–3 win over Bray Wanderers as Limerick's form improved which saw them stay in the Premier Division with games to spare and also saw them narrowly miss an FAI Cup Final at the Aviva Stadium as they lost 1–0 to Munster rivals Cork City in the Semi final. St Patrick's Athletic 2018 season On 1 December 2017, Clarke signed for his third Dublin club, St Patrick's Athletic ahead of the 2018 season. On 9
