Northern Ireland midfielder Michael O'Connor has joined up with his international team-mate Ryan McGivern after signing a one-year contract with Port Vale.
The 26-year-old was released by Rotherham United at the end of last season, despite being part of the squad that made it back-to-back promotions from League Two into the Championship.
O'Connor returns to the area having started his career with Vale's local rivals Crewe Alexandra.
"Michael is a real quality player," said Vale manager Mickey Adams.
"I'm sure the fans will like what they see when Michael plays because he's an all-round midfield player. He can pass, he can score goals and he's really competitive."
Another Northern Ireland international who helped his club gain promotion to the Championship last season has also joined a League One club.
Will Grigg, who scored five times as Brentford went up behind Wolves, has been allowed to join MK Dons on a season-long loan – much to the delight of manager Karl Robinson.
"I'm absolutely over the moon. He's the one I've wanted for the last 12 months," said Robinson.
"When he played against us for Walsall, I thought he was an outstanding talent. He's a name at this level, he's a goalscorer at this level and he's a Northern Ireland international too."
