Cameron Anson: Before a ball was kicked, alarm bells were ringing for how lightweight the Liverpool midfield is. Simply can't impose themselves.

David D: Liverpool's plan of having all the possession doesn't matter if all they do is kick it into the defenders on the edge of the box.

John Stirzaker: Can we only shoot straight at the keeper??

Liverpool have now kept only three clean sheets in their last 20 FA Cup games. Is that an area they need to strengthen in the summer?

"I would say its been an average first half, but it's been quite enjoyable seeing Liverpool try to create chances against the massed ranks of the Crystal Palace defence. There are thoughts for both sides at the break. Can Palace cause more problems for Liverpool in the second half? Or will Liverpool continue to have the lion's share of possession?"

So Crystal Palace are 45 minutes away from an FA Cup quarter-final. Can Liverpool turn this around after the break? They have had enough ball to win two games, but there were signs at the end there that their tempers were beginning to unravel...

Simon Brotherton
Match of the Day commentator

"An FA Cup tie finely poised thanks to Simon Mignolet's late first-half save to deny Crystal Palace a second goal. Pape Souare, on his debut, was living dangerously with a challenge on Daniel Sturridge in the penalty area, but it is Palace who lead with a goal from Fraizer Campbell."

Dwight Gayle is getting under the skin of the Liverpool players. That's the third time Gayle has gone down easily and Daniel Sturridge is furious with him. Picking him up angrily. Calm down!

Fais Sam: Palace have truly developed into Liverpool's bogey team. Pace to burn and a lively atmosphere. Credit where it's due!

"Crystal Palace have created chances but so far there has been very little controlled passing from the home side. They are defending resolutely though - determined, dogged defensive work.

"Alan Pardew is kicking every ball in the technical area. He will be more than happy to reach half-time in front, but I do think Palace look a little bit vulnerable down the left-hand side, where Daniel Sturridge has found space a few times."

Dwight Gayle for 2-0... no! Gayle should score, he's in behind the static Liverpool defence again but all credit to Simon Mignolet, out quickly and making himself really big to save with his left ankle. A big moment.

More of what Lazar Markovic is all about as he picks the ball up on the right, drives inside, commits two defenders, beats another - but then shoots over from 20 yards on his left foot. He's a dangerman but without enough end product right now.

Liverpool have completed more than double the amount of passes as Palace, but for all their play they've only really put one quality move together, when Adam Lallana had a shot well saved. Palace are ahead and happy to sit back and hit on the break.

"What with Daniel Sturridge claiming for a penalty (see 30 mins) there have certainly been some early decisions for the referee to make, that's for sure. I always go with that great Yorkshire expression: 'If in doubt give nowt.' All of these decisions are so marginal."

Liverpool still turning on the pressure, as Joe Allen fires a volley just wide from 20 yards. Into the last 10 minutes of the first half.

Asking Jordan Henderson to shoot himself seems a bit harsh...

Khalid: "Henderson needs to work on his finishing. He should have shot himself rather than set up Lallana."

If you haven't seen Fraizer Campbell's opener you can watch it on this page now. Just click on the highlights tab at the top of the page.

Jordan Henderson is booked for a tussle with Dwight Gayle - there didn't appear too much, if any contact - and Henderson then lashes in a shot which is turned away by Julian Speroni.

Great save - and then Daniel Sturridge wants a penalty as he collects a bouncing ball - no dice!

Charlie: "Pardew could really build a solid cup run if Palace win today."

Ade: "The one negative about Liverpool at the minute is we can be a little Arsenal like (i.e. we must literally walk the ball into the net)."

Anonymous: "As a neutral, it's disgraceful how Palace have evidently over-watered the pitch. Have they got longer studs than the Liverpool players?! It's ruining the game and if any goals are caused by or prevented by slippages, surely it's a form of cheating?"

Martin Skrtel must have nightmares about Dwight Gayle. Gayle tormented him to score twice in that classic 3-3 draw at the back end of last season, has already mugged him in the build-up to Palace's goal tonight and now gets past him again, skinning him inside the box. He's such a livewire.

"Crystal Palace need a little breather here. Liverpool are applying the pressure. The home side need to get some passing passages together because although they've got the cushion they haven't established any rhythm yet. This is a big challenge for Jordan Henderson playing in the central midfield position for Liverpool, the position Steve Gerrard has filled for years."
