First things first, some perspective. Theo Walcott scored 108 goals in 397 appearances for Arsenal, at a rate of a goal every 3.7 games.
At his best, Walcott's raw, inhibited speed electrified Arsene Wenger teams. He was the pocket rocket that helped his side storm back to draw 2-2 against Pep Guardiola's brilliant Barcelona in 2010.
He scored crucial goals to seal Champions League qualification against Udinese in 2012. He has scored several memorable goals in impressive Arsenal victories over Arsenal.
For England, he produced arguably the greatest individual performance of the current Millennium on the night he cut Croatia to ribbons as a 19-year-old in 2008.
