[1] Farren began his football career with a largely unsuccessful period, throughout which he was dogged by injury, in the youth setup at Tranmere Rovers.

However, he returned to the form he showed in 2005 and did manage to hold down a regular spot in the team, with an especially strong finish to the season, which helped Derry win the FAI Cup.

[5] Farren, who scored in the 1–0 victory in the last game over Monagahan United to give Derry the championship, may however be forced to put his playing career on hold due to a brain tumour.

He's been unbelievably courageous, I don't think people realise how brave he's been, although certainly all the players do.He was named in the squad travelling to Sligo to play in a crucial league match at the start of September 2011.
