Paul Robinson has returned to Millwall to become The Lions' Under 23 Elite Development Squad assistant manager.
Robinson, 37, arrives back in SE16 to take up a role in assisting current Under 23s boss Kevin Nugent, with the Professional Development League season set to get underway in August.
The former centre-back is no stranger to Millwall supporters - with 361 appearances and 23 goals to his name, 'Robbo' famously captained the club to its 2009/10 League One Play-Off Final triumph, scoring the winner at Wembley Stadium against Swindon Town.
On his departure from The Den, the defender played for Portsmouth, AFC Wimbledon and lastly Havant & Waterlooville, where he combined playing with coaching, taking up a role alongside former Lions boss Kenny Jackett at Fratton Park.
Millwall's Under 23 Elite Development Squad 2019/20 fixture list will be released in due course.
