Mousset scored on his first Premier League start for Sheffield United

Sheffield United claimed a stunning win over Arsenal to move into the top half of the Premier League.

Lys Mousset marked his first start for the Blades with the decisive goal in the first half, turning in Jack O'Connell's knockdown from close range.

Arsenal's £72m signing Nicolas Pepe had earlier skewed a golden chance wide from six yards.

Granit Xhaka forced Dean Henderson into an excellent save but the Blades closed the game out superbly for a famous win.

The victory was Sheffield United's biggest result since their return to the Premier League as they moved up to ninth, four points clear of the relegation zone.

Defeat for Arsenal, meanwhile, means they missed the chance to move back into the top four. They are fifth, two points behind Chelsea in fourth.

Sheffield show their steel once again

Sheffield United have certainly shown plenty of grit on their return to the Premier League and have been particularly impressive in not rolling over to sides in the top six.

They battled from two goals down to draw 2-2 at Chelsea in August before pushing Liverpool close at the end of last month, only to be undone by a single goal from a mistake by Henderson.

Against Arsenal they again took the game to their opponents from the outset. David McGoldrick's technical ability combined with Mousset's pace posed a troubling front line for the Arsenal defence.

Chris Wilder had challenged his new-look forward line to give the Blades the cutting edge they have lacked this season and Mousset did just that, making the most of being unmarked inside the box to sweep home.

From then on, it was all about the Sheffield United defence. The hosts, incredibly, have not lost a league game when leading at half-time since 2014 and they managed the remainder of the game superbly, with their back three of O'Connell, Chris Basham and John Egan forming a formidable barrier.

"I have so much respect for Sheffield United's back three," BBC Radio 5 live summariser Chris Sutton said. "They have come up through the leagues together, they are well oiled and well drilled.

"It is the best defence in the Premier League this season, along with Liverpool."

Travel sickness strikes again for Arsenal

The Gunners went into the international break in a good place in the Premier League.

They sat third after beating Bournemouth 1-0 at the Emirates, extending their home record so far this season to four wins and one draw.

But away from home Arsenal remain unconvincing.

Their only win on the road in the Premier League came in their season-opener when they beat Newcastle 1-0 but since then they have scraped draws against Watford and Manchester United and lost to Liverpool and now Sheffield United.

Arsenal have won just four of their last 17 games away from home - a statistic Gunners boss Unai Emery will need to improve quickly if they are to challenge for the top four.

Pepe fails to produce the goods

Pepe's miss in the first half was arguably a big turning point in the game

Ivory Coast winger Pepe arrived at Arsenal in the summer with a big reputation and a big price tag.

The £72m club-record signing had scored 35 goals in 74 appearances for Lille, but he has been underwhelming so far for the Gunners.

The 24-year-old had scored one goal - a penalty - in nine appearances prior to Monday's game and should have really got his second for Arsenal but managed to miss a chance that looked considerably easier to score.

But despite that error he was arguably the best player in an admittedly under-performing Arsenal team in the first half, and it is easy to forget that it was he who started the move in his own box that led to the chance he missed.

However, Arsenal fans will understandably be expecting him to perform on a more consistent basis to justify his huge price tag.

'There was a very clear penalty' - what they said

Arsenal boss Unai Emery: "We deserved more. I think the first half the very clear chances were for us. Then we conceded more corners than we wanted and they scored one from a corner. There was a very clear penalty and I think VAR is for that.

"The second half the defence was more deep and had good control of the match. There was less space in the second half but we still had three or four chances. We deserved more but they are a very strong defensive team.

"We created 12 corners for us and we conceded seven or eight. They score one goal from one corner.

"We prepare for the matches the same home and away and think to win."

Sheffield United boss Chris Wilder: "We have deserved to win a tight game. We knew they would have some chances and have a lot of the ball.

"I thought we got the balance tonight. We had to put in a big performance and get a big result. The players know what is expected of them. We have to play, we have played to get into this division and we have to play to keep in the division.

"It is Arsenal, no disrespect it is not a League One team but we have managed to win a tight game at home."

On goalscorer Lys Mousset: "Brilliant for him. He is a really popular boy. He took a bit of time to get up to speed but he had something for us that was a little bit different."

Bramall Lane blues for Arsenal - the stats
