They marched through their league campaign with a confidence and panache their opponents simply could not match.
The side managed by Noel Byrne made sure of the crown with a 2-0 win over Woodbine and followed that up with a 9-2 trouncing of Wheel Madrid.
"We got a decent crop of players and we jelled together, there's a great team spirit among the lads," said captain Derek Murphy.
The team came about when a group of former footballers got together at the start of the season, decided to give it another go and transformed themselves into champions along the way.
It's a remarkable story and a great advertisement for the LFL and the facilities it can offer new clubs.
Captain Murphy also pointed to the great "backroom team" who provided the players with the necessary direction and support.
There is manager Byrne, assistant Mick Cody, secretary Alan Bolton.
There are others, added Murphy, such as Derek Connolly who ensures everything is ready before games; that the nets are in place and the pitch is properly marked out.
As Islandbridge's success indicated while you need the players on the pitch the work behind the scenes is just as important.
Yet is hasn't been all plain sailing for Islandbridge. They lost out in both the Sheeran and Dalton cups.
They're still in the Haroldville and they would have to be strong contenders to win it outright and make it a league and cup double.
Rialto have the scent of Sheeran in their nostrils
Cup specialists Rialto are on the scent of the Sheeran Cup and are looking good to take the trophy.
The Dolphin Road outfit have not one but two teams in the semi-finals.
Paddy Lyne's Sunday side booked their place in the last four when they defeated AIB 3-2 with two goals from Dave Foran and one from Mark Long.
The Saturday side are also through with player/manager Ross McNally scoring from what one observer called a "fabulous" header to earn a 1-1 draw.
Rialto won the penalty shoot-out. Galty Celtic and Cashel Celtic are the other two teams left in the shake-up.
Dynamo look to the future
Dublin Dynamo FC are a new club but they clearly intend to be around for the long haul.
The multi-cultural club is planning to form an under-age set-up to ensure a conveyor belt of talent for the future.
The youngsters won't lack for the proper direction and advice it seems as six members of the team recently embarked on an FAI coaching course.
Clubman Victor Ilnitskyy says the club, which is supported by Smith's of Phibsboro, are anxious to ensure that Dublin Dynamo has the talent coming through to keep the flag flying.
