Peterborough goalkeepers Joe Lewis and James McKeown are spending the week training with Manchester United.
Posh manager Darren Ferguson has sent the duo to his father's club while he searches for a replacement for former goalkeeping coach Andy Dibble, who has left London Road because of family reasons.
Ferguson was keen for the pair to continue receiving specialist coaching so he can concentrate on the outfield players.
"Three coaches were highly recommended to me and I spoke to them all this week," he said.
"They are all strong candidates for a very important position and I will get one of them in soon.
"Joe and James will spend the week at United and come back to us next Monday to start preparing for the Bristol City match.
"It means Kevin Russell and I can concentrate on the outfield players."
