Larrieu began the 2008–09 season behind former Arsenal man Graham Stack, but returned to the side in the 2–1 win at Watford and kept his place for the remainder of the season, proving to be as influential as ever in his 40 league appearances. In recognition of his performances throughout the season, Larrieu was voted as Plymouth Argyle Player of the Year by the club's supporters. As of the 2009–10 season he was appointed the club captain. Larrieu was sent off in the final game of the 2010-11 in English football season for deliberate handball. On 5 May 2012, Larrieu announced that the club's final match of the 2011–12 campaign against Cheltenham Town would be his last as a Plymouth Argyle player, allowing him to concentrate on his coaching duties.
