Chelsea goalkeeper Lucas Bergstrom says he enjoyed last season's loan with Peterborough.
Bergstrom appreciated the chance to play for Posh regularly.
He told the club's website: "I really enjoyed it. Playing Tuesday-Saturday every week, the focus was always on the games. Training almost became secondary, so it was a very different approach.
"I didn't feel it was a huge shock; people say that first loan into men's football can be. Maybe it was because I came from Finland and the facilities were more similar.
"The biggest thing was to learn to play for the points. Nothing else mattered. Win at all costs."
