Arsenal 2-0 Man Utd: Xhaka and Aubameyang seal the victory of the Gunners – 5 talking points

Arsenal is placed at the top of the standings to rank in the top four with a 2-0 win over Manchester United at Emirates.

The Gunners outscored their opponents in fourth place with the win – and found themselves one point behind Tottenham, their rival in North London, ranked third.

Unai Emery's men scored a goal in both halves, Granit Xhaka helping to break the deadlock in the long run. The shot deviated and went wrong David De Gea in goal United.

Pierre-Emerick Aubameyang doubled his advantage from the penalty spot after Fred's defeat by Alexandre Lacazette in the box.

Here are five points of discussion of the Emirates …

1. The six Lukaku records questioned

Jamie Redknapp confused the viewers of Sky Sports by claiming that Romelu Lukaku just looked in plain sight, while a graph appeared showing his goal count against the "big six".

In simple terms, it is not very good.

To be fair, the Belgian looks more like the attacker than one knows to be under the orders of Ole Gunnar Solskjaer, but he fought at the Emirates.

Nourished with a superb deep pass from Fred in the second half, Lukaku failed to wrap up the match and Bernd Leno saved the ball.

As the saying goes, statistics do not lie.

2. Changes made by Emery are not free

They used to call Claudio Ranieri the Tinkerman, but Arsenal boss, Unai Emery, is trying to qualify for the crown this season.

He made five changes to the team, although weakened, who lost to Rennes in the Europa League midweek but who reaped once again the fruits of his success.

Mesut Ozil made a rare start against a direct rival and posted a strong performance while Ainsley Maitland-Niles did no harm to his reputation.

3. What difference does a goalkeeper make

David De Gea may well be one of the best goalkeepers in the world, if not the best, but his mistake in the first half cost United – and his opponent kept Arsenal in the game.

Gary Neville's theory that De Gea is distracted by his ongoing contract discussions may be in the headlines but is obviously wrong.

For his part, Bernd Leno explained why the position of the # 1 gunner was a topic of discussion over the years.

Until the arrival of Petr Cech, there were many question marks on Manuel Almunia, Lukas Fabianks, Wojciech Szczesny and David Opsina, but Lukaku's decisive rescue of Leno kept his side.

4. Clubs must act against intruder fans

Just hours after Jack Grealish 's assault by a Birmingham supporter at the Second City derby, a supporter went to the UAE field to celebrate Arsenal' s second goal.

On the way to the players, he pushed Chris Smalling and exasperated Paul Pogba before being removed from the pitch.

Pitch invaders are not new – they are often naked and drunk – but this new breed will surely see someone get hurt seriously, or worse, for too long.

Clubs must do more than banish thugs in retrospect.

5. The day of St Totteringham?

Arsenal fans have long been resigned to finishing a little further than their bitter rivals this season, but their recent rebirth – and Tottenham's tottering form – saw them narrow the gap by 10 points 16 days ago to a single game in eight games.

It is likely that Tottenham will take the Champions League more seriously than the Gunners do in the Europa League (if they progress), which could see the red half of London congratulate her again.
