Phil Parkinson has opted for 4-5-1 in today's cup match against Sheffield United at Bramall Lane. Burton is alone up front with Ambrose behind him in the hole. Moutaoukil starts at right back with Youga on the left. Holland is recalled and Rob Elliott resumes his role between the posts.
Therry Racon is fit enough to warm the bench and he is joined by 17-year old Jack Clark. The left back is a second year scholar and makes his first appearance with Charlton.
