The Old Trafford massacre prompted Arsene Wenger to return to the transfer market, which resulted in a flurry of panic buys in a bid to fortify the squad for the upcoming campaign.
With the 2012 window almost closed, it is almost exactly a year since the five last-gasp signings were sanctioned; but what impact have the players had at the club so far?
Were the transfers really just knee-jerk reactions, or were they a wise and justified move on Wenger's part?
This article analyzes how effective the new faces were in their debut season.
Note: the list does not include Gervinho, Carl Jenkinson or Alex Oxlade-Chamberlain as they were all signed by the club before the defeat to Manchester United, thus they were not a part of the five late summer signings that Wenger made.
