Celtic performance consultant and former Donegal football manager Jim McGuinness has said there are many similarities between the two teams, and "that the dynamics are exactly the same".
As part of wide-ranging interview, his first for radio since stepping down as Donegal manager earlier this month, McGuinness also expanded upon his role at Celtic, where he has worked as a performance consultant since late 2012.
He said that his role had changed this season with the appointment of Ronny Deila, and that he was likely to be working almost exclusively with the Celtic first team in the months to come.
There are many similarities between Celtic’s and Donegal’s styles of play, McGuinness said.
“[Deila] wants to play a very high-octane brand of football,” he said.
“[There are] a lot of similarities between Donegal [and Celtic]. It’s high-energy, it’s high-intensity, it’s very demanding. But it’s very offensive; I’ll put that in before somebody else puts it in!
“But the thing about it is, the dynamics are exactly the same, it’s just you’re trying to do it in a different area in the pitch.
“In terms of game plan and tactics, it’s so close. [There’s] a lot of energy expanded, and something the manager talks an awful lot about is energy levels. Because it’s very demanding he wants players that are happy and high energy levels, and that obviously makes my role more important.”
McGuinness also said he owes a lot to Europe's successful Ryder Cup captain, Paul McGinley.
He attended this year’s Ryder Cup at Gleneagles, where McGinley's captaincy was praised highly by Europe's players, as a guest and is known to have provided advice to the Dubliner.
McGinley’s father, Mick McGinley, who is from Donegal, had initially told McGuinness that his son was keen to meet when he was captain of the Great Britain and Ireland team in the 2011 Seve Trophy.

“Paul probably had aspirations at that stage of being the Ryder Cup captain, so he was interested in getting a handle on management, in terms of team dynamics, and I suppose the psychology side of it and what I had done with Donegal," McGuinness said.
McGuinness said that he had had many questions for McGinley, and that since they first met he and McGinley had become close friends and sources of advice.
“We talk a lot,” McGuinness said. “Paul has had a massive role in my career as Donegal manager, as has his father, and he has been a great source of counsel for me. I owe him a lot.”
