The former Chelsea boss has been given the blessing of the current administrators of the crisis-club to leave and Grant has decided to hand in his notice, seemingly in order to take the reins at the Boleyn Ground.
The outgoing manager parted company with Portsmouth by giving this statement to their official website.
“This was one of the most difficult decisions I’ve had to take in my football career. After a lot of soul searching and under the circumstances I’m taking a different direction."
"It’s been both a difficult and complex year for us at the club, but at the same time, it’s been a wonderful and uplifting professional and personal experience. I will never forget the loyal fans of Pompey who, without a doubt, helped me protect the team under such complex circumstances. There are very few teams in the world that have fans as passionate and devoted as you are.
"It has been a great experience to be part of one of the most wonderful occurrences that has happened in the history of British football and also shows that even in the most desperate times, loyalty, devotion, professionalism and passion can be demonstrated.
"I wish you all the possible success which you genuinely deserve. Portsmouth has given me a feeling of home away from home. I might be leaving Portsmouth physically, but you cannot take Portsmouth away from me and my heart."
