   • 2012 September 7, Phil McNulty, “Moldova 0-5 England”, in BBC Sport‎^[1]:

     If Moldova harboured even the slightest hopes of pulling off a comeback that would have bordered on miraculous given their lack of quality, they were snuffed out 13 minutes before the break when Oxlade-Chamberlain picked his way through midfield before releasing Defoe for a finish that should have been dealt with more convincingly by Namasco at his near post.
