Ranger was considered as one of the brightest young talents to have emerged from English football in recent times but following a number of unsavoury off-field incidents, the 24-year-old is currently struggling to find a club.
London-born Ranger has now gone on to admit that a lack of discipline has let him down and believes that he could have become a regular for Newcastle as well as being called up to the England national team alongside former youth teammates Danny Welbeck and Daniel Drinkwater if only he had managed to 'behave'.
"Sometimes I watch Newcastle and know I'd definitely be playing right now, especially with how things are going for them.
"There are times where I have seen them play and thought, 'I can do better than that'. But I can't always hold on to that because it is done now."
