David Button has been transferred to Charlton Athletic. "The Academy graduate, who turned professional in February 2006, made one appearance in our colours in the League Cup against Doncaster in 2009, with the England Under-20 international having gained experience on loan at 11 different clubs, the most recent being in the Championship with Barnsley last season."
