Colin Munro Re-signs With Brisbane Heat Until 2026
Aston Villa have signed former England midfielder Ross Barkley from Luton Town, both clubs announced on Monday.
Neither team disclosed the details of the deal but British media said Barkley has penned a three-year contract at the Premier League club.
The 30-year-old is set for his second stint at Villa Park following a loan spell from Chelsea during the 2020-21 season.
Barkley will join a Villa side who finished fourth last season and will compete in the Champions League this term.
"With additions to the already great squad that we've got it's going to be pivotal for the season," Barkley said.
He played a key role for Luton last term, making 32 league appearances, although they were relegated from the top flight. He also has 33 caps for England with six goals scored during his time with the national team.
