Peterborough have signed Walsall midfielder Dean Keates and defender Chris Westwood on three-year contracts.
Keates, 28, was the Saddlers captain and top scorer last season with 13 goals, while Westwood, 30, was a regular starter in central defence.
Manager Darren Ferguson, who played with Westwood at Wolves, told the club's website: "I am delighted to capture Dean and Chris.
"They are both good professionals and good signings for this football club."
Both players were selected in the League Two team of the season, with Keates named Walsall's Player of the Season.
Peterborough chairman Darragh MacAnthony said: "It's a great compliment they have made my club by signing three-year deals.
"They are both convinced they want to be part of the success that Darren and I want to bring to the club.
"Let's hope we will all be celebrating promotion again as champions."
