Peterborough signed 22-year-old striker Lloyd Opara on loan from Southern Premier Division side Cheshunt until the end of the season.
Opara had previously spent time on trial at Premiership side Chelsea.
"We've been trying to bring Lloyd to the club for a while and I am pleased to have signed him," Posh boss Steve Bleasdale told the club's website.
"He will give us another option in attack, he is very quick and loves to get in behind the defence."
The loan deal has been agreed with a view to a permanent move in the summer.
