Charlton Athletic have dominated Birmingham City in the opening 45 minutes, but the score remains 0-0.
The Addicks had the first real chance of the game early on when a clever free kick from Johnnie Jackson found Dale Stephens, but his effort was deflected wide.
Charlton came close again minutes later when Stephens back-heeled to Ricardo Fuller, who beat his man and forced Jack Butland into a fine save.
A neat move from Charlton created a chance for Yann Kermorgant, but his shot was deflected behind for a corner.
On 29 minutes, Lawrie Wilson had the best chance of the game when he was found at the near post, but he could only head wide.
Fuller was involved again for the home side and showed great skill to control and create space for a shot that went just wide of the far post.
