Nile Ranger has issued an apology to all his former clubs for his off-the-pitch behaviour.
The 24-year-old recently reported back to League One club Blackpool – 10 months after going AWOL.
And Ranger – who spent almost five years at St James’s Park – is looking to relaunch a once-promising football career.
But Blackpool manager and former Newcastle player Neil McDonald is unwilling to given the striker another chance.
Ranger’s colourful Newcastle career was punctuated by off-the-field incidents, and the club’s patience finally ran out in early 2013.
And he has issued a belated apology to United as well as Blackpool and the other teams he has represented.
“I just want to take the time out to write this post as I feel like I need to get this off my chest,” he write.
“I have seen two of my good friends pass away in a short space of time. Whilst overcoming this it has made me realise life really is too short and have really been taking things for granted.
“I would like to use this opportunity to thank, Southampton, Newcastle, Swindon and Blackpool for giving me the chance to experience the dream of being a professional footballer.
“To add to this, I would like to apologise to everyone at these clubs, including management, players, staff and fans. I should have given more and been a better role model.”
Ranger, a former England Under-19 international, hopes to “get back on the pitch and play.”
He added: “Truth be told I’m just a young boy who has been living the dream and playing a game which I do love and miss deeply, and hope that one day I will be able to get back on a pitch and play because life is really too short.”
