Millwall boss Neil Harris believes Tony Craig will be a vital link between the team and the Lions' faithful after he rejoined the club from Brentford.Defender Craig, 30, started out with the Lions, coming through the youth ranks, then moved to Crystal Palace in 2007 before returning to the Den in 2008.
He made a switch to Brentford in 2012 and spent three years at Griffin Park prior to rejoining the Lions for a third time, dropping down into Sky Bet League 1 in the process.
"I have said a lot about the fans being able to identify with their team and Tony Craig is certainly a player that fits that bill," the manager told millwallfc.co.uk.
"He will link the team and the supporters together and is a natural leader within a young squad.
"We will have youthfulness and energy within the team, but you also need experience and Tony will bring that in abundance. He is a great leader in the dressing-room and is a warrior on the pitch.
"He has huge know-how about this football club and this division. I'm delighted to get him back."
