Forest Green Rovers have signed versatile forward Sean O’Brien on a free transfer.
The 20-year-old, who can play as a central striker or attacking midfielder, has joined the League One newcomers after a successful trial.
“Sean impressed us and we think he has a lot of potential,” head coach Ian Burchill told the club website.
“He’s a clever footballer who’s very comfortable on the ball and has a lot of positive attributes.”
O’Brien has spent all his fledgling career with Millwall and appeared for the club’s under-18 and under-21 sides before his release at the end of last season.
