Ex-Newcastle striker Nile Ranger has 'a lot to prove' as he eyes League One contract

The former Newcastle United youngster has not played competitive football since January and has been without a club since his contract at Southend United was terminated for 'reoccurring disciplinary issues'.

But the 27-year-old has been handed an opportunity to impress at League One side Oxford United where manager Robinson has kept a watchful eye on the striker's progress.

And while claiming his off-field behaviour has been 'impeccable' during his spell with the club, Robinson insists he won't be rushed into making a decision on Ranger.

"He still has a lot to prove to me," said Robinson, speaking to BBC Radio Oxford.

"It's a decision I have to make with the club in mind.

"It has to be right for the football club first and foremost. Hopefully, Nile falls into the morals and personal standards that I believe this club should uphold.

"But at the same time, I don't like to prejudge people without getting to know them, regardless of the past. You serve your sentence and you should be judged on who you are today."
