The Irishman played a pivotal role in Derek McInnes' side finishing fourth in the Scottish Premiership. He made 37 appearances, scoring once, as well as notching one assist.
It's been a big summer of change so far, not least in the dugout and upstairs with Malky Mackay's arrival, but on the field as well with Paul Hanlon, Lewis Stevenson, Adam Le Fondre, Dylan Tait and Jacob Blaney all departing.

Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
