Knockaert wins Leicester another corner... (IL) #CAFCLive
37' Patient build-up play from Leicester ends with De Laet crossing into the area and Vardy heading wide. (IL) #CAFCLive
39' Wide! Mahrez, on his full debut, cuts in from the right wing, goes past Poyet, and shoots wide from 20 yards. (IL) #CAFCLive
41' Harriott booked for a sliding challenge on De Laet. Perhaps a touch harsh that one. (IL) #CAFCLive
PRESS DAY: We are awaiting Chris Powell's arrival for his FA Cup press conference at The Valley. We'll bring you quotes shortly. #cafc
Good hassling from skipper Johnnie Jackson in front of the away end. Nobody looked more determined than him pre-match. (IL) #CAFCLive
9' Corner headed over by Sheffield United. Not easy for goalkeeper Ben Hamer with the midday sun in his eyes. (IL) #CAFCLive
14' Ryan Flynn booked for cynically pulling back Harriott as he tried to breakaway. (IL) #CAFCLive
16' Slightly fortunate free-kick given to Charlton after a challenge on Jordan Cousins. (IL) #CAFCLive
The Addicks are a bit nervy in possession early on here. Could do with a spell of possession to calm it down. (IL) #CAFCLive
17' Corner to Charlton after a skewed clearance. (IL) #CAFCLive
Inviting corner from the skipper, but it eludes everyone in the area. Sun definitely a factor in both boxes so far. (IL) #CAFCLive
21' One-two between Church and Tudgay ends with the former shooting weakly at goal with his left foot. (IL) #CAFCLive
22' Callum Harriott tries his luck from distance, but it's straight at Howard. (IL) #CAFCLive
25' Nice passage of play from Sheffield United ends with Jamie Murphy shooting wide of Hamer's right post. (IL) #CAFCLive
30' Chance! Deflected effort from Tudgay is saved low by Howard. Closest we have come so far. (IL) #CAFCLive
31' Doyle takes out Church after a nice pass from Harriott. Maybe a booking from some refs, not this one. (IL) #CAFCLive
32' Free-kick to Sheffield United. Now Harriott the player perhaps fortunate to escape a yellow. (IL) #CAFCLive
35' Good defending from Rhoys Wiggins to clear danger, but Simon Church now down after a collision with Maguire. (IL) #CAFCLive
38' Jackson booked for a lunge at Flynn, after Poyet gave the ball away. Home fans want a red. Never a sending off, though. (IL) #CAFCLive
40' Sheffield United put the ball in the net, but it's ruled out for offside. (IL) #CAFCLive
42' United very much on top as we count down to half-time here. Still 0-0 at the moment. (IL) #CAFCLive
Three minute of added time here. (IL) #CAFCLive
45+1' Chance for 'sufc as Maguire strides forward from defence, not for the first time, before Harris shoots just over. (IL) #CAFCLive
