Evening all, and welcome to AFC Bournemouth v Arsenal!

Surman lofts a ball forward for Solanke and Mustafi challenges, taking a clattering off Martinez who heads clear. Mustafi stays down clutching an ankle - he landed awkwardly - play continues, and when the ball goes out the physio comes on. I think that might be him done for the evening.

The crowd now boo Guendouzi - grown adults, booing - and Gosling trips him to various cheers.

Guendouzi trips Surman, but avoids a card once more.

Surman curls the ball in, a few men fall over, and Martinelli heads away well. VAR checks for a penalty, but there is none.

Well this is promising. Guendouzi dawdles over the ball when Bournemouth have a free-kick so Gosling waves a leg at him and Guendouzi reacts, shoving him over. Players congregate, Lacazette takes his mate away, and the ref disburses a lecture.

Smith goes in late on Martinelli, who goes down; the ref allows play to go on, Arsenal play on, Bournemouth win the ball and play on, then play is stopped. Cook S is deeply unhappy, but it was a foul.

I guess Bournemouth improved in the 15 minutes before half-time, but I'm still a little surprised Eddie Howe didn't make a change or two. He's got Callum WIlson on the bench, but not much else.

Willock wins a corner down the left and "soaper Nick Pepe" comes over to bang it against the first man.

If Arsenal win tonight, this round will have seen the fewest from home teams since the cup was reorganised in the 1920s.

Off we go again.

Bournemouth were disgraceful for half an hour, but a little better thereafter; Arsenal have been excellent.

Half-time: Bournemouth 0-2 Arsenal

Arsenal break through Nketiah and Wilson slides in - that's a good challenge, and one of the first we've seen tonight - but the ref deems it a foul, on which basis he's obliged to show a yellow card.

There'll be two added minutes.

Bournemouth win a corner down the left, Surman goes short to Wilson, and he scuffs his cross straight to Sokratis.

It's ridiculous how many brilliant young players England have.

All perfectly normal.

Fraser has livened things up and he moves infield to open space for Simpson outside him. The ball indeed goes thataway, but the resultant pull-back is well-read by Xhaka and Arsenal clear.

Have Bournemouth woken up? Wilson comes inside onto his left foot and swerves in a cross for Gosling, who tries to glance a header but can only impart a shoulder, lopping the ball onto the roof of the net.

Bournemouth attack! Fraser goes down the left and crosses well; the ball is nudged away from Solanke by Xhaka, but as the ball drops, Wilson gets a good look at it, and clouts a volley that Martinez does well to beat away at his near post.

If I were Alexandre Lacazette, I'd be extremely concerned. He doesn't score enough goals to be centre-forward in a team challenging for honours unless the wide players are prolific, and Arsenal's are not. I'd not be at all surprised if he got sold in the summer.
