It's been a good start by Sheffield United this second half. There is a sense of urgency about them.

It's going to be interesting for Sheffield United because when you get relegated, you only need one or two of your players to think that playing in the Championship is easy, having just come from the Premier League. But it doesn't work that way, you're going to be a massive scalp in that league.

Strong, driving run from Oliver Burke sees him power around Calum Chambers, but the Arsenal man recovers well to clear.

Can the Blades fashion a chance to go with this smart start?

James: Chance for Lacazette to step up while Aubameyang is no where to be seen.

Weenson: Surely Arsenal cannot afford to lose Lacazette in the summer.

A really bright opening. John Fleck's final pass into the area is behind Oliver Burke which is a shame for the Blades as that was a good move, before Ben Osborn thinks he has won a corner but a goal-kick is given instead.

John Egan makes a nuisance of himself again at a set-piece but can't trouble Bernd Leno with his header. Bright opening from the hosts though.

"Like a night out in Sheffiiieellldd..."

We're under way.

Here come the sides once more.

Alexandre Lacazette has now scored 49 Premier League goals for Arsenal. He can become the 10th player to score 50 PL goals for the Gunners and the fourth from France, after Thierry Henry (175), Olivier Giroud (73) and Robert Pires (62).

Some trio!

This is the seventh time Arsenal have led at half-time in the Premier League this season, winning each of the previous six.

Craig Smith: This game is a great opportunity for Martinelli to get a goal and kick start his Arsenal career again. As for Arsenal, an opportunity to get their confidence back for Thursday.

Arsenal are very much in charge of this game. It was an outstanding goal and it's very difficult to see where Sheffield United will go in the second half. Nothing wrong with their effort, but it's just the lack of quality, I'm afraid.

And that's the interval. A pretty good game lit up by an absolutely gorgeous goal.

Sheffield United 0-1 Arsenal

Arsenal whip in a corner and VAR wants to check for a possible handball against Oli Norwood.

Nope.

Nine of Alexandre Lacazette's 12 Premier League goals this season have come away from home.

But then Sheffield United win their first corner, it's not dealt with and John Egan hits a rasping shot at Bernd Leno and it nearly goes right through him.

Daniel Cheng: When it works it works. Pretty football great goal.

Andrew Sanders: Can we hold onto a lead and maybe get a clean sheet?

Grumpy Expat: ‘The Invincibles’ would have been proud of that Arsenal goal.

Gabriel Martinelli now sees a shot deflect just wide after a corner cane out to him. Was actually brilliantly blocked. The youngster fancies a goal tonight.

He scored against the Blades at the Emirates last year, one of the last games I went to. Feels about 10 years ago.

What does Paul Heckingbottom say to Sheffield United now in the dressing room? What can he possibly say? There is still a bit of steel about the players that they have got, though (excuse the pun).

Camatriix: Arsenal goal that. Quality move.
