"It is a really good cup tie and a fantastic atmosphere at Ewood Park."

"Blackburn started brightly and got the first goal, but they couldn't go 10-15 mins without conceding.

"Dimitri Payet's free-kick is wonderful and there only looks one winner in this.

"Blackburn will have to have a go to get themselves back into this game. They were a little surprised by scoring and it got West Ham going.

"West Ham are a big, strong, athletic side and in full flow, they are hard to handle. If they get the next goal, they will run away with the tie."

Paulinator Maximus: this season as a hammers fan you know 2 things: 1- that we will start slowly; 2 that Dimi will score from a free kick.

It was a slow burner, but it ended up being an appealing first-half of FA Cup football.

West Ham deservedly ahead, but Blackburn have very much played their part.

It's the Dimitri show though, folks.

If anyone gets full marks for persistence, it's Rovers' Chris Taylor.

He nicks a loose pass from James Collins, aimed for Dimitri Payet, and then bundles through Angelo Ogbonna and Pedro Obiang on the way to making an opening for himself. The shot is tame though, and Darren Randolph gets down to it easily.

Edmund Emiowei: Take a bow Dimitri Payet - another peach of a goal from one of the players of the season! Are you watching, Didier Deschamps?

(It was Dimitri Payet in case that wasn't obvious).

James Collins meets it but nods over.

West Ham win a corner. No prizes for guessing who's taking it...

It seems so long ago, but Rovers were leading at one point. Here's that goal.

Low, hard, precise.

A fine goal from Ben Marshall to open the scoring. We'll bring you West Ham's equaliser shortly, and then Dimitri Payet's free-kick at some point too.

That's eight for the season for Dimitri Payet. What a signing he has turned out to be.

The 7,000 Hammers who have traveled to Lancashire are happy. Is this their year?

"Dimitri Payet was level with the post and it bent so much it almost clipped the post on the way in. Fantastic execution to get it up over the wall, have pace and direction on it too. Stunning.

"It is a difficult one for the goalkeeper, he knows where it is going but you have to stand on one side of the goal in case he tries a cheeky one.

"What a fantastic skill for Payet to have though, it is almost like taking a penalty for him.

"Maybe if he waited another week to sign his new contract he could have got £140k a week."

"Blackburn have done really well because they are staying in possession, they are not dropping and staying on their feet.

"They are saying to West Ham, 'you're going to have to play through us'."

Chris Taylor in the book for clipping West Ham's Dimitri Payet on the edge of the area...

Paul Lambert is saying things reasonably aggressively to people on the Rovers bench.

Just seeing some TV replays of a goal-kick Jason Steele took moments before that Victor Moses equaliser. The Rovers keeper seemed to pull up after he hit the long ball - did that affect his ability to get down to the Moses shot?
