It's been a torrid start to the season for Arsenal and something needs to change - quickly.

A harrowing 2-0 loss to Brentford on the opening night of the season has seen the pressure mount on boss Mikel Arteta after just one match.

Arteta is already in hot water after just one game at Arsenal

Perhaps what was most alarming is that many expected the top-flight's newcomers to come out with three points.

The Bees outplayed the Gunners all over the park to seal their first Premier League victory ever.

And diehard Arsenal fan Darren Bent, who hit 106 goals for a handful of Premier League clubs in his career, conceded that top four is well out of the Gunners' reach following their opener.

"I think we get can top eight," Bent told Drive on Wednesday. "You've got to be realistic.

"We know it's not good enough, but you've got to be realistic with where they are.

"In terms of recruitment, signings, you see where they are. It's sad to see, but that performance against Brentford just wasn't good enough."

Arsenal are in deep trouble, with fans at boiling point and Arteta on the brink.

So what needs to happen for the north London club to have a good season?

The £35million signing of Martin Odegaard, who impressed on loan after joining in January, is a great start.

The Gunners have been crying out for more creativity and the Norwegian adds exactly that - but more arrivals must follow.

Arteta will also need to make tactical tweaks if he is to salvage the season.

We at talkSPORT.com have identified those tweaks and who else needs to come in following their disastrous start to the new season.

More signings

Many fans think Arteta should be sacked, but chopping and changing bosses may not be the best of solutions, particularly as Antonio Conte is the only world class manager available and he's unlikely to take the job.

What's alarmingly clear is that Arsenal must get more signings through the door, with little under two weeks left of the window.

If they don't, real trouble could follow.

Albert Sambi Lokonga, Ben White and Nuno Tavares have all arrived for a combined fee of around £80million, but the inexperienced trio do not have enough to help the club work their way back into Europe.

A striker, another creative midfielder alongside Odegaard and another right-back is what Arsenal need.

Would Coutinho be a good signing for Arsenal?

It understood there are negotiations with Barcelona over a potential swap deal involving Pierre-Emerick Aubameyang and Philippe Coutinho

A report from Spanish outlet Sport claim Gunners skipper Auba would 'welcome' leaving north London after Arteta's side failed to achieve European football for this season.

Coutinho for his part would return to the Premier League after he became one of the world's most promising attacking midfielders at Liverpool.

We know he's supremely talented, but it would represent a risk worth taking bringing him back to England given his form in Barcelona.

However, it could reinvigorate his career and spark the club into life this season.

Meanwhile, Arsenal are also weighing up a move for Fiorentina hitman Dusan Vlahovic, who impressed with 21 goals in Serie A last term.

Aaron Ramsdale, who was the Player of the Season for relegated Sheffield United, is also closing in on a move to the Emirates.

Coutinho and Vlahovic would add some much needed firepower to Arteta's ranks, while Ramsdale will offer them strength in depth - something every successful side needs.

A new right-back will also need to be brought in if the unsettled Hector Bellerin does leave the club, with Cedric Soares ageing and Calum Chambers not a natural right-back.

Build team around Saka and Smith Rowe

Saka was a shining light in what was a desperately disappointing campaign for Arsenal last season.

He deservedly won the club's Player of the Season award and emulated his impressive displays on the international stage with England at Euro 2020.

Arsenal must build their team around the versatile winger - as well as his academy teammate Emile Smith Rowe.

The latter was one of the few outstanding performers against Brentford.

Smith Rowe and Saka have been players Mikel Arteta has been able to rely on the most

He drove at the defence was never afraid to pick out an ambitious pass.

It seems incredible that Arsenal's two best players are so young, but Arteta must build his team around the talented duo if he wants his side to have a good season.

Get best out of Partey

The midfielder had a difficult first season in the Premier League and that was mainly due to string of injury setbacks.

Arsenal are yet to see the quality of the Ghana international following his £45m switch from Atletico Madrid last summer.

He missed the Brentford clash, but must hit the ground running when he returns.

Arsenal's defence is their weak point and Partey's disappointing debut season played a part in that last term.

A fit Partey could see a change in fortunes for the club.
