Therry Racon believes he is joining a 'big club' after agreeing a two-year contract to join Millwall from Charlton Athletic.
Skysports.com revealed earlier on Tuesday that Racon was undergoing a medical at Millwall ahead of finalising a free transfer move to The Den.
The Lions beat off competition from several Championship clubs to land Racon and the 27-year-old is looking forward to playing for Kenny Jackett's side.
"As soon as my agent told me of Millwall's interest I was happy to sign here," Racon told the club's official website.
"Millwall are a big club and coming here will be a good challenge and opportunity for me back in the Championship.
"I know Hameur Bouazza from our time together in France and I know about the fans from having played here for Charlton.
"I've played at The Den only once and it was a nightmare! We lost 4-0. But I know what it's like with the fans and I can't wait to play in front of them."
