The Gunners spent more than £200 million last summer, but still don't have a squad strong enough to win the Premier League

Mikel Arteta and Declan Rice both said the exact same thing after Sunday's 2-1 loss at Fulham: "Not good enough." And they were right. Arsenal didn't deserve to take any points home from their trip to Craven Cottage, so dire was their display.

The real concern for the Gunners, though, is that same phrase could be applied to their squad. As it stands, Arteta's men don't look remotely good enough to challenge for this season's Premier League title.

Rice added on , "There are a lot of media who talk and say Arsenal are going to win the league this year and we are better this year, but we don’t get involved in that." Which is the right approach, really, because it wouldn't do anyone connected with the club any good to dwell on the fact that the squad is actually weaker now than it was last season – and that's a deeply depressing thought for the fans, given the club spent more than £200 million ($250m) during the summer transfer window.

Rice, to his credit, has proven an excellent acquisition. His goals alone have been worth five points to Arsenal, and that's without getting into what he adds to the midfield. Jurrien Timber was also desperately unfortunate to suffer a serious injury on his debut after impressing in pre-season, but the decision to spend £62m ($78m) on Kai Havertz remains as baffling now as it was last July. The Germany international has enjoyed something resembling a mini-revival in recent weeks, but there's still no shaking the feeling that Arsenal's ambitions would have been far better served by signing a proven goalscorer.

However, it's been made abundantly clear during the first half of the season that Arsenal aren't just short up front. Indeed, a squad that was meant to challenge for the title is alarmingly short in several key areas…

Arteta can't be criticised for wanting an upgrade on Aaron Ramsdale, who is error-prone and poor with the ball at his feet, and David Raya looked like the right addition, given how impressively he'd performed at Brentford last season.

However, despite the constant support of his manager, Raya has looked very, very shaky at times this season, and been beaten by shots that never should have got past him. The Spaniard just doesn't inspire confidence and that's a major problem for a back four.

There's no suggestion that Arsenal will look to sign another goalkeeper this month, with Arteta clearly set to stick with Raya, but rather than solving a problem, the manager has unintentionally created one.

Arsenal looked quite well-stocked in this position before the season began, given the impressive versatility of Timber, Ben White, Jakub Kiwior, Takehiro Tomiyasu and Oleksandr Zinchenko.

However, Timber might not return until March, White's form has fluctuated wildly, Kiwior is a liability at left-back, as the Fulham defeat hammered home, Tomiyasu has had his injury issues and is now off to the Asian Cup, while Zinchenko's defensive deficiencies have been repeatedly exposed.

Consequently, many supporters have questioned the wisdom of the decision to allow Kieran Tierney to leave on loan to Real Sociedad, as some still consider him the best left-back on Arsenal's books.

Whether the Scot would have made a major difference to the title tilt, we'll never know, but what's clear is that unless Arsenal dip into the transfer market – or recall Tierney – they're going to have issues on either side of the defence until Timber returns to full fitness.

White, Tomiyasu and Kiwior can all play at centre-back, but it's honestly come as no surprise to hear rumours of Arsenal trying to signing Matthijs de Ligt, given the Dutchman has struggled to lock down a starting spot under Bayern Munich boss Thomas Tuchel.

William Saliba and Gabriel Magalhaes obviously make for a solid pairing. Indeed, if the former had not missed the end of last season, Arsenal may well have held onto their lead at the top of the Premier League. As it was, the back four capitulated without Saliba, which only underlined Arsenal's fragility without the Frenchman. Another spell on the sidelines really would put paid to their title aspirations.

So, while Timber's return will ultimately give Arteta another excellent option to play alongside Saliba, they look worryingly short on quality at centre-back right now. In that sense, selling Gabriel would appear out of the question, but the Brazilian, who was heavily criticised by Ian Wright for his performance at Fulham, is prone to dropping clangers and if the incessant Saudi Arabian interest in his services materialised into a solid bid, the money made could be put towards a more reliable partner for Saliba.

Rice was touted as the missing link for Arsenal, the kind of player that could propel the club to a first Premier League title since 2004. However, while the England international has made a big impact, he's not proven a game-changer because the make-up of Arteta's midfield is still not right.

Thomas Partey's injury issues obviously haven't helped, even if Arteta was using the Ghanaian as a right-back during the early stages of the season. One imagines that if Partey had stayed fit, he would have eventually been used in his preferred deep-lying, play-making role that would have offered greater protection to the back four, while at the same time allowing Rice serve as the link-man between the midfield and the attack. With that option unavailable, the latter has often been asked to do far too much from a defensive perspective, given he's often got two No.10s (Martin Odegaard and Havertz) for company in the engine room.

Of course, Partey is now poised to return to action, but doubts remain over his future as a mooted move to Saudi Arabia would allow Arsenal to at least partially fund a move for another defensive midfielder. Still, while talk of a move for Fulham's Joao Palhinha makes an awful lot of sense – the Portuguese showed Arteta exactly what he's missing in the middle of the park with a tremendous display at Craven Cottage on New Year's Eve – one wonders whether Arsenal would have sufficient money to make it happen, given it's believed that they'll have to sell before they can buy this winter.
