Rory Gallagher suffered defeat in his first competitive match as Donegal manager as his side were comfortably defeated by Derry in Owenbeg.
Rory Gallagher fielded a very experimental side in the Dr McKenna Cup opener with neighbours Derry and handed senior debuts to a number of players.
Eamon Ward, Conor Parke, Ciaran McGinley, Eunan Doherty, Eoin McHugh and Willie Gillespie were all handed their competitive debuts.
Dungloe star Cory Gallagher was also handed a starting berth at right-half-back but he has experience in this competition after playing in the Dr McKenna Cup in 2013.
Martin McElhinney, Dermot Molloy, Michael Boyle and Mark McHugh added some experience to the team.
Brian McIver named a strong and experienced side and that showed throughout the game.
Derry completely dominated the match and they particularly enjoyed dominance in the middle sector of the pitch.
Emmet McGuckin was the stand-out performer during the match and his goal separated the sides at half-time.
He was outstanding throughout and was ably assisted by Mark Lynch and Benny Herron.
Despite their dominance Derry only led by three points at half-time.
Derry 1-05 Donegal 0-05.
Rory Gallagher made a series of changes in the second period and handed other senior debuts to Joe Gibbons, Ryan Melley and Malachy McDermott.
But in truth Donegal were completely outfought by a determined and resilient Derry side that really stepped up through the gears in the second-half.
There greater experience and quality showed and they powered to a comfortable win over their bitter rivals.
Rory Gallagher can take plenty of positives from the match with a number of the debutants performing well.
Gallagher will be able to experiment further in their other two Dr McKenna Cup matches against Fermanagh and Queens University.
Final score Derry 1-16 Donegal 0-08
