Charlton have strengthened their squad with the signing of former Southend midfielder Alan McCormack on a free transfer.
Southend agreed to cancel the contracts of McCormack and his team-mate Adam Barrett, who has since joined Crystal Palace, after a request from the pair.
McCormack has now linked up with the Addicks and manager Phil Parkinson is delighted to have acquired the 26-year-old's services.
"I'm really pleased to have Alan on board," he told the club's official website.
"The thing that struck me about him more than anything else was his hunger.
"Anyone I bring into this club this summer, whether it's a member of staff or a player, has got to relish the challenge, as I am doing, because it's going to be a challenge this season.
"Alan fits the bill in terms of his enthusiasm and his hunger to join Charlton.
"He's a player I've watched many, many times and I always come away admiring his performance. We look forward to working with him."
