Derek Mazou-Sacko has signed a 'long term' contract at Millwall

Millwall have signed French midfielder Derek Mazou-Sacko from Ligue 2 side Rodez AF.

The 20-year-old has joined for an undisclosed fee and signed a "long-term contract" at The Den.

Last season he made 31 appearances in the French second tier, scoring once, and is a former Under-18 international.

"He's a player we've tracked for some time and he fits the profile of the type of talent we want to bring into the club," director of football Steve Gallen told the club website.

"Having played in France's second division he has shown qualities that have impressed me every time I've watched him.

"Derek is an exciting, progressive midfielder who is comfortable on the ball and has the ability to drive us forward."
