Millwall have agreed the signing of young midfielder Ashley Grimes from Manchester City and he will put pen to paper at The Den on July 1.
The 21-year-old worked with Lions boss Kenny Jackett during his spell as youth-team coach at Eastlands.
Grimes has not managed a first-team appearance for City during his time at the club, but he spent a month on loan with Swindon early last year.
"I will be joining Millwall because I see this as a great opportunity to play regular first-team football for a club that clearly has the potential to progress to the Championship," he told the Lions' official website.
