Example: 2012 December 29, Paul Doyle, “Arsenal's Theo Walcott hits hat-trick in thrilling victory over Newcastle”[1], The Guardian:
  Four minutes later Walcott, who until then had been redundant as a lone striker owing to one-star service, was given his first decent pass of the game and duly took his chance to outshine the Senegalese, springing a poorly conceived offside trap to collect Lukas Podolski's ball and stroke a low 15-yard shot past Tim Krul and into the far corner.
