Man Utd beat Rochdale on penalties after 1-1 draw
Liverpool through, Oxford hammer West Ham
Chelsea hit seven, Sunderland beat Sheff Utd, Villa see off Brighton
Burton beat Bournemouth in game delayed three times for floodlight failure
Burton Albion 1-0 Bournemouth
Looks like we're going to get playing again. The lights have gone off on three occasions (I think) in the second half. There must come a point when it's just unfair to continue? ALthough I suppose a replay would also not be much good for Bournemouth.
Mason Greenwood
Breakthrough!
A star in the making?
Two goals in two games for Mason Greenwood, finding space down the right edge, cutting in and drilling a confident, low finish into the net.
Finally the home fans can breath a sigh of relief.

Love Pellegrini, love our league form, love that we are challenging the top six. However... What I would love more is to see my team lift a trophy for the first time in my lifetime and I'm not that young. Sadly this is yet another wasted opportunity and the fans deserve better.

Seeing the name Moore on the scoresheet against West Ham just seems wrong

The number of Manchester United attempts on the Rochdale goal is rising - but still no sign of a breakthrough goal for the hosts.
Manager Ole Gunnar Solskjaer and assistant Mike Phelan have both taken turns in the technical area but the presence of neither man has triggered a change in fortune.
Rochdale are working so hard.
Reece James (82 mins)
Reece James scored some crackers at Wigan last year while on loan and here's another one, his first for Chelsea.
The ball falls to him 22 yards out and he curls in in style.

Edward Taylor: It's not just at the ground where there is electricity supply issues. It's happening across the rest of Burton and East Staffordshire.
Burton don't seem to know for sure...

Ruaidhrí Ward: No United fan is underestimating Rochdale, Nick (21:07). The only thing we underestimate these days is the wearing psychological impact of supporting United.
MK Dons 0-2 Liverpool
Good cup tie this! MK Dons could have one back but again Jordan Bowery has a header well saved!
MK Dons 0-2 Liverpool
MK Dons back off, and back off Alex Oxlade-Chamberlain and he thunders a long-ranger against the foot of the post.
Matt Taylor
Oh my goodness, Premier League side West Ham are heading out!
Sub Matt Taylor converts a low cross at the far post and League One Oxford are in dreamland.
19 minutes to hold on to a famous victory.

Grimsby - to their credit - are throwing men forwards and leaving themselves open at the back. Could be more goals to come.

Andy Townsend
Ex-Chelsea midfielder on BBC Radio 5 live
Well played the young right back Hoever. He's got himself in a really good position and it's the man at left back, Milner, who puts it in. The right back comes in and plays a thunderous header and that should be enough to take Liverpool through.
Man Utd 0-0 Rochdale
United go towards the Stretford End and come close to breaking the deadlock themselves, but Mason Greenwood's clipped effort at the near post is kept out well by Rochdale goalkeeper Robert Sanchez.

Keith Hill
Bolton manager on BBC Radio 5 Live Sports Extra
A great phase of play, counter-attacking, passing. He very narrowly missed an unbelievable opportunity but well defended by Manchester United.
