Ryan Leonard has initially joined Millwall on loan until January 2019, where he will complete a club record undisclosed fee move to The Lions from Sheffield United.
A long-term target of Neil Harris', the 26-year-old central midfielder made his professional debut in March 2010 at Plymouth Argyle - the club whose youth ranks he rose through - as they took on Blackpool at Home Park.
Leonard then moved on a free transfer to Southend United, where he spent seven years and made over 250 appearances, becoming a firm fans' favourite and attracting interest from clubs in Leagues above The Shrimpers.
The midfielder signed for Sheffield United for a undisclosed fee in January 2018, but was captured by Harris and The Lions on Deadline Day in August 2018.
