Despite controlling the game, Donegal couldn’t get the scores in the first 35 minutes.
But the manager admitted his team got it right in the second half with a deluge of scores.
“I wasn’t overly impressed at half time but we pushed on in and in the second half and there was more fluidity . There was a bit of pressure and they wanted to put the best forward in front of their supporters,” he said.
The Glenties man said the game sets them up for the semi-final against Tyrone in Clones in two weeks time.
“It’s good to get over the line and sets up a big game for us. We are happy we have achieved that and we will refocus the minds now
“They have worked very hard for past 18 moths and have tried their best foe their county – they train hard and are very focused. Hopefully we can continue on and get a positive result the next day,” he said.
He admitted that Letterkenny man Rory Kavanagh almost started the game but will almost certainly feature the next day out.
“Michael (Murphy) felt he wasn’t going to take a chance but he felt he was ready. Rory (Kavanagh) was close but he felt a bit of a nip and hopefully he can put his best foot forward and we want to get him back.”
And McGuinness also responded to claims that Donegal were now shedding their so-called ‘defensive game.’
“We have a different plan all the time and everyone is changing. It’s not secret we are trying to get more scores on the board.”
