Nacho Monreal’s comments highlight Arsenal’s lack of depth in this area

Arsenal defender Nacho Monreal says that he feels strange playing at centre-back, but he may have to get used to it this season.

Arsenal manager Arsene Wenger should be concerned by Nacho Monreal's latest comments as they highlight a major flaw in the club's squad at the moment.

Whilst there is a huge amount of optimism around the Emirates Stadium and the starting line-up looks as strong as it has in many years, there is an obvious deficiency in the squad which was exposed by Monreal's comments.

Arsenal only have two bespoke centre-backs in their senior squad - Per Mertesacker and Laurent Koscielny - and whilst they make a quality pairing, the Gunners' lack of depth in this position could cost them.

Monreal came out today to say that he felt strange playing at centre-back, and this should be a massive worry for Wenger. 

"I feel a little bit strange because it’s not my natural position,” Monreal said. “I have only played it two or three times, but the boss one day named me in this position and I will try to do the best [I can].”

The Spaniard is a full-back by trade, yet he is likely to have to fill in at a position that he admits to not feeling at ease in on fairly regularly occasions this season.

Although Mertesacker and Koscielny will be the regular selection in the two spots in the Premier League, Arsenal will have to compete in four competitions this season and there is no way the two can play every game.

Their first choice cover is Calum Chambers, but he is another player who has spent most of his career so far at full-back.

Although Chambers has performed well in the heart of defence so far, even Wenger has admitted that he doesn't see his long-term future there - the Frenchman has taken a huge risk by not singing a specialist centre-back as cover in the summer transfer window.

Thomas Vermaelen was available to use last season and provided brilliant back-up, but any long-term absence at centre-back for Arsenal could prove hugely costly this year.

There were plenty of defenders available for Wenger this summer, but he is famously prudent and it seems it could be set to cost his side again if the worst case scenario does occur.

Of course, it may not be a problem if everything goes swimmingly at the North London club, but, without a contingency plan in place, it seems a risk that they did not need to take.
