Plenty of expectation as Jay Emmanuel-Thomas lines up a 25-yard free-kick. The big man approaches with purpose but his strike is tame, and Adrian is able to easily hold on to it.

West Ham readying some substitutes.

Only a whisker away from the opener for the hosts! Alan Hutton with the classic overlap from right-back, his early delivery is a cracking cross too and Andreas Weimann meets it, powerful header but just past the post. That's got the fans going.

Steve: New contract for Fabian Delph! Chuffed but what is he thinking?! Can we cause an upset and beat Bournemouth now?!

The Championship leaders look very settled and confident at Villa Park. We all know what Middlesbrough managed yesterday, can the Cherries strike another blow for the Football League?

West Ham have made a steady but solid start to the second half, they are certainly not letting City get off to the flying start they managed in the first half.

"Both sides are moving the ball around very quickly but I have been particularly impressed by Bournemouth. Their passing is very accurate, and they are also having shots on goal. They look very attractive. We've heard a lot of things about Carles Gil for Villa. It will be very interesting to see how he gets on in this game."

Arsenal

Plenty of pace in the Arsenal side today as Mesut Ozil and Theo Walcott both start. Ozil's first start since September.

Good defending from Villa centre-half Jores Okore prevents Shaun MacDonald from running clear on goal, the Cherries looking lively as MacDonald then shoots over the top.

And we are back up and running at Ashton Gate.

"I think Sam Allarydce could change formation for the second half. I think he might go 4-5-1, with Andy Carroll up top, just to try and shore the game up. Allardyce will be happy to take a draw and a replay back at Upton Park. Too many of the West Ham players have not been at it."

Under way at Villa Park.

"The important thing for a young manager is getting the respect of his players and Eddie Howe has got that. He has a good backroom staff with him and some very good players, a great spirit too. If he can get promotion to the Premier League - they remind me of Burnley under Sean Dyche. It will be an unbelievable achievement. Going to Villa Park, if they can get through the first 20 minutes, the crowd could get edgy and turn on the Villa players."

"Aston Villa are a wonderful club, a really big club not just in Birmingham but in English football. Paul Lambert has recognised that he has to keep clean sheets, so they are defending a bit deeper and maybe the results will pick up for them."

"I stand by what I said on the BBC Sport website, Aston Villa are embarrassing in terms of scoring. Only 11 goals in the Premier League. There are lots of problems. Christian Benteke is not scoring as many as he has in previous seasons, but Gabriel Agbonlahor and Andreas Weimann aren't scoring either. And in midfield, Villa only have one assist all season between them. Looking at the midfielders in the team, I still fancy them now, at my age. The strikers are not getting enough chances created for them."

"The news of Fabian Delph signing a new deal with Aston Villa - amid reported interest from Liverpool and Spurs - has certainly lifted the spirits of the home fans. Now they need the extra lift of actually scoring a goal and even winning a game here against Bournemouth in the FA Cup fourth round."

Villa Park is a long, long, long, long way from full. Bournemouth have made eight changes, can they still shock Villa with their second-string?

"Bristol City have been working extremely hard. I have seen them a few times this season, they really work hard for each other closing players down, forcing slack passes from West Ham. Who is the Premier League team here again? Watching the clips at half-time you would definitely say it was Bristol City. West Ham have to make some changes. They need more energy to get into the game."

"Luke Freeman is a very good player. He is very good at finding space. His end product has let him down but he goes at the back four. West Ham will have to sort that out. He has been the one real creative force for Bristol City but just hasn't found the right final pass yet."

Fabian Delph has only scored three league goals in 96 appearances for Villa - can he add them to his game now he has a new deal?

He doesn't play today.

"West Ham have struggled to contain Matt Smith. As well as being a physical presence, he also has the ability to hold the ball up and bring his team-mates into play."
