Scotland: Mark McGhee aims to shine alongside Gordon Strachan
Mark McGhee concedes he has a point to prove as assistant to Scotland manager Gordon Strachan.
"I see those two episodes (at Aberdeen and Bristol Rovers) as failures as well," McGhee said.
"So yes, I think I have questions to answer and I think I can only do that below the surface."
McGhee, 55, said he had no hesitation in accepting Strachan's invitation to join his backroom staff.
"I was kind of hoping I would get that call and when it came I was delighted," said McGhee at a media conference at Hampden.
McGhee guided Rovers to 13th position in League Two last season. However, a run of nine defeats in 11 matches saw him part company with the club.
"I think I have questions to answer and I think I can only do that below the surface," he said.
"I am not the manager, I am not there as the number one; all I can do is give Gordon as much support and make him the best manager I possibly can and hope that people see the job I'm doing and appreciate it."
McGhee is philosophical about the turbulent nature of management and revealed he still harbours ambitions of managing again in his own right one day.
"I am not the only manager who has lost his job and got another job, that's what happens," he said.
"Anyone who looks closely at circumstances and situations in any football job, will know that there are more than one side to every argument.
"People get sacked and get jobs again. What you have to do is not be blase about that and expect that every time you get the sack you are going to get another job.
"I think you have to be determined and I feel very unfulfilled as a manager, regardless of the successes that I have had, and I have had a lot of successes.
"But I feel unfulfilled as a manager. I imagined that I would spend my whole life managing in the Premier League and I haven't so I still have things to do and getting an opportunity at this level is okay."
