This week Jim McGuinness decided to use his Irish Times column to air some of Donegal's dirty linen in public. The Celtic coach hit out at the treatment handed down by the Donegal County Board to some of his former players following the 2014 Championship campaign.
McGuinness is less than happy that for their sacrifice, seven of his squad have been unable to receive a holiday that was owed to them. And while many have commended McGuinness for looking after player's welfare, one man who's less than enamoured with the former Donegal boss' gesture is his old foe Kevin Cassidy.
The two men have quite a bit of history after Cassidy was thrown off the Donegal panel by McGuinness in 2011 for contributing to a book entitled 'This Is Our Year'.
Earlier this year, Cassidy broke his silence on that acrimonious parting of ways by revealing McGuinness' final words to him as he left the squad.
We parted company and as I made my way down the stairs of the Clanree Hotel Jim shouted: ‘And remember you are bound by that legal document and you can never talk about anything when you leave here’.
It's fair to say Cassidy isn't too bothered by that warning because he's used his Gaelic Life column this week to fire some shots at McGuinness in light of the holiday complaints.
[McGuinness] must have a short memory because it wasn’t that long ago that he blocked my wife and I from going on a team holiday. The phrase; pot, kettle, black springs to mind!! But then again for me the words Jim McGuinness and hypocrisy go hand in hand!
Cassidy was dropped by McGuinness at the end of the 2011 campaign and was subsequently blocked from going on the team holiday despite having been a key part of the squad throughout the campaign.
