Arsenal's sole senior acquisition so far this transfer window was a goalkeeper, with Petr Cech arriving from Chelsea in late June.
Since then there has been much clamour from supporters for the club to purchase further players, with a striker and an additional defensive-midfielder the most obvious necessities required to bolster the squad.
In addition, though, Arsenal should be looking to bring in another goalkeeper, perhaps on loan, before the transfer window closes, with their current predicament leaving them just two injuries away from having to field a relatively untried youngster in high-profile fixtures.

Cech, despite struggling in his first two Premier League fixtures, has quickly established himself as Arsenal's first-choice goalkeeper, with David Ospina acting as his deputy.
However, the decision to send both Wojciech Szczesny and Emiliano Martinez on loan for the season, to Roma and Wolverhampton Wanderers respectively, has left the club considerably light in the goalkeeping department.
Arsenal's other options are inexperienced
Matt Macey, who turns 21 next month, is currently acting as third choice but, despite the fact that he has produced some impressive performances for Arsenal's Under-21 side since joining from Bristol Rovers two years ago, he is very inexperienced with regards to senior football and endured a difficult loan spell with Accrington Stanley last season.
Macedonian youngster Deyan Iliev, meanwhile, possesses good reflexes but is also rather error prone and at 20 he is also yet to be tested at the highest level.
Beyond him, young goalkeepers Ryan Huddart and Hugo Keto possess much promise, but are aged just 18 and 17 respectively, so, although they could train with the first-team on some occasions, it would surely represent a major risk to deploy them in senior games at this fledgling stage of their careers.
Another goalkeeper is required
With all that considered, it surely makes sense for Arsenal to bring in another goalkeeper on loan during this transfer window as, otherwise, it would only take injuries to both Cech and Ospina to leave them having to field Macey against the likes of Manchester United.
One element of concern is that a potential new signing would take up a place in the club's Premier League squad, with Arsenal currently having just two slots remaining for new foreign acquisitions. However, with Joel Campbell's future still uncertain, a space could well open up for a back-up shot-stopper.
It may well be the case that a new goalkeeper, if one does arrive, wouldn't even feature at all for the first-team, as was the case with Emiliano Viviano, who spent the 2013/14 campaign on loan at the club. It is better to be safe than sorry, however, to ensure that the club doesn't find themselves in a precarious position with regards to their goalkeepers.
