"It was a near thing for a red card, but the referee was in a good position and had no doubt. They have to watch out for the pace of Liverpool on the break."

"It was a near thing for a red card, but the referee was in a good position and had no doubt. They have to watch out for the pace of Liverpool on the break."
Silly from Bolton captain Matt Mills. He gets sucked in by Raheem Sterling, who flicks it over his head and is in behind and Mills can only haul him down. Booking.
KoloKK: , externalHow many games have Liverpool won this season without Lucas? Dicey against Bolton.
Liverpool cannot defend a corner convincingly at all. A Bolton ball form the right skids across the face of goal, Emile Heskey is close to connecting and it ends up as a volley for Matt Mills. He shanks it though. At the other end, Liverpool finally have a strike on goal as Jordan Henderson lashes in left-footed and Adam Bogdan makes the stop.
David Southall: Spurs gone, Chelsea gone, Manchester City gone, Southampton gone, Everton gone. Big chance of silverware for Manchester United and Liverpool now!
Pav Dhande: All these ridiculous, completely unexpected wins now of course means Aston Villa will win tomorrow...
Chris Clarke: The only way this day could get better is if Emile Heskey scores a winner against Liverpool.

Javier Manquillo is taken out - in his view anyway - off the ball by Dean Moxey but the referee waves play on. Sloppy from Liverpool so far as now Joe Allen squirts a pass out of play.

"The chances for Steven are looking a little brighter than they did earlier, but Liverpool have got to get past this first."
Manchester City manager Manuel Pellegrini, speaking to BBC Sport: "Before they scored the first goal, we had five or six clear chances. They didn't have one chance. But we conceded a very easy goal, and the game changed. We were nervous. They are a team who work well; that's why they are second in the Championship. They had opportunities to score more goals and deserved to go through.
"Now we must continue in the Premier League and Champions League. I wanted to continue in all the competitions but now we must focus on the Premier League and Champions League. We now have a difficult game against Chelsea, We must reduce the five-point gap."
Asked if he thought City's trip to Abu Dhabi had tired them out: "No, I don't think so. It's easy to have an excuse, but I don't think that was the case."
Bolton still seeing all of the ball, Liverpool hardly getting out of their half so far.
Impressive start from Bolton, dominating the ball in the fledgling stages at a noisy Anfield. They win a corner, Emile Heskey flicks it on and Emre Can just about scrambles it out. Not convincing.

"United are still alive, but there were a few games today I could not have forecast. But that's what we have loved about the FA Cup for all these years.
"Bolton have done well since Neil Lennon came, and I genuinely think they have a chance. Liverpool have a strong team here, and they are going for it."
Emile Heskey wins his first header in front of the Kop, rolling back the years. He can still win headers, but he hasn't got the pace of old of course. He's still a brute of a man.
Southampton boss Ronald Koeman: "It's not normal that a team like Crystal Palace - with all due respect, because they played very well - creates so many possibilities.
"At least we had a good reaction in the second half, but it wasn't enough. We like to play offensive football, but we need communication in the defence to work together.
"We'd like to win every game, but we know our level and we have to be good to win games like this."
Koeman also confirms Shane Long has a suspected rib fracture.
Ten years ago these sides finished level on points. Quite a lot of water under the bridge since then but can Bolton do a Bradford? Or a Middlesbrough?
"You'll Never Walk Alone" rings out at Anfield. Are we on for another FA Cup classic?
Mark David Boden:, external Refreshing to see that money isn't everything in football. Hard work & dedication allow the seemingly impossible to be achieved.

I went to see Bolton play a few weeks ago and I can tell you that if you give Eidur Gudjohnsen space, he can still do it. Great touch, great vision. No pace...

"Huge congratulations to Bradford City and Middlesbrough. Truly stunning performances!"
Anfield is packed to the rafters for tonight's late game. Where do we go from here? Heskey hat-trick?
