Port Vale have completed the signing of defender Adam Eckersley on a free transfer from Manchester United.
The 22-year-old left-back recently had a short loan spell at Vale Park, making just two appearances before picking up a knee injury.
"It's a new thing for me. I have been at Manchester United since I was nine years old," he told Vale's website.
"I believe we have got a good chance of staying up in League One and I am happy to be back. It is a good club."
