The former England boss has had an awful start to the campaign with Forest, and hoped to make transfers before the deadline closed.
“I can’t deny that it has been a frustrating time and some things have not worked out the way I had hoped in the first three months but it is a building process and still very much early days.
“I would like to emphasise that my only concern is getting on with the job at Forest and achieving the goal of taking the club back into the Premier League.
“Contrary to reports, it has never been my intention to consider leaving. I’m certainly no quitter and I am as enthusiastic about the task as I was on the day I arrived in Nottingham in June.”
