Watch Vieira’s stunning strike here:

The 22-year-old, who joined the Gunners from FC Porto in a deal worth £34 million in June, received the ball 25 yards from goal and unleashed an unstoppable left-footed strike past Brentford goalkeeper David Raya.

It was a moment of magic from the Portugal Under-21 international, who also started in Arsenal’s 2-1 win over Zurich in the Europa League earlier this month.

What a hit!

You can see from his delayed celebration that he didn’t realise his shot had gone in at first.

But it was a beautiful strike that left Raya with absolutely no chance.

What has Mikel Arteta said about Fabio Vieira?

After signing Vieira in the summer, Arteta described the Portuguese as a “special talent”.

“I am very excited that we have identified and signed such a special talent,” the Spaniard said at the time.

“Fabio is a very creative player that will bring high quality and versatility to our attacking play.

“We welcome Fabio and his family to our club and are looking forward to starting work with him ahead of the new season.”

Technical director Edu added: “We’re so pleased to have completed the signing of Fabio from FC Porto.

“Fabio is a player with special qualities who is comfortable with the ball in the final third of the pitch.

“We are all looking forward to working with him and enjoying his future contribution to Arsenal.

“We will now continue to work hard and are looking forward to finishing this transfer window as strongly possible.”

Arsenal impress against Brentford

This was an impressive team performance from Mikel Arteta’s side, who leapfrog Tottenham and Manchester City to return to the top of the Premier League table.

William Saliba opened the scoring in the 17th minute with a flicked header from a corner before Gabriel Jesus doubled the visitors’ advantage.

Vieira’s goal early in the second half then effectively wrapped up all three points for Arsenal, who head into the international break sitting pretty at the top of the table.
