The Mirror today posted an article claiming Arsenal have improved their injury record from 2013-2014 to 2014-2015 by 25%, quoting numbers probably lifted from the notoriously inaccurate Physio Room. These numbers are completely incorrect. We've been tracking Arsenal injuries on a daily basis since the start of the 2013-2014 season, and the difference is not even close to 25%.

In 2013-2014 we lost 2,084 days in total, over 69 injuries. In 2014-2015 we lost 1,827 days in total, also over 69 injuries (although Welbeck is also included there so it's more like 1,900 days over 70 injuries). So in the best case scenario, the difference between the seasons was around 10%.
