Input: Question: What position did Samuel play when he took over for Sabajo while making his Morton debut? Passage:Samuel was offered the chance to join Greenock Morton of the Scottish Championship on loan on transfer deadline day at the start of September 2015, an offer he stated he "knew straight away" that he wanted to take. He signed a four-month loan contract with Morton, with the deal running until January 2016. He made his Morton debut as a 78th-minute substitute for Romario Sabajo in a 4–2 away victory at Livingston on 5 September. Samuel became a regular in the first-team for Morton almost immediately, scoring his first two goals for the club in a 3–2 extra-time Scottish League Cup win over Motherwell at Cappielow in his fourth appearance for the club. His first goal in the match came courtesy of a sweeping effort in the first-half, before netting the winning goal in the 100th-minute with a first-time finish from a low cross. Samuel scored his first Scottish League goal in the Renfrewshire derby, scoring the equalising goal from close range in a 1–1 draw away at St Mirren on 20 November 2015. He added a fourth goal to his tally for the season on 18 December 2015 when he scored midway through the first half to briefly give Morton the lead in an eventual 2–1 home defeat to Raith Rovers. In January 2016, his loan deal was extended for the rest of the 2015–16 season. A month later, he briefly returned to Swansea to receive treatment after sustaining a knee injury in a Development League West match against Queen's Park. The injury ultimately ruled Samuel out of action for a month, before returning to the Morton first-team as a late substitute in a 3–2 win over Queen of the South on 15 March 2016. He went on to feature largely from the substitute's bench for the remainder of the season, making 30 appearances and scoring four goals in all competitions during his time at Morton, with the club finishing in fifth place in the Scottish Championship.
