I see you got there first - bloody work getting in the way mid-post!No they don't lie and you've kind of helped prove my point with your post. Of those 9 knockout goals, 6 have come against:
Ukraine x 2
Columbia x 1 (pen)
Denmark x 1
Senegal x 1
Slovakia x 1
And against top level opposition, just 3, 2 of which were penalties:
Netherlands x 1 (pen)
France x 1 (pen)
Germany x 1
And I'm not sure of the relevance of bringing in Rooney, Owen, Shearer and Lineker's stats is but as you have, Kane has played nearly as many knockout games on his own as those four put together so he should have more goals!:
Rooney - 5 knockout games
Owen - 4 knockout games
Shearer - 3 knockout games
Lineker - 5 knockout games
Total - 17 knockout games
Kane - 14 knockout games
So all of them except Rooney (who was also over rated, padded his stats in friendlies and qualifiers and didn't perform in tournament after peaking at 18 - but that's another debate), had better scoring ratio's in knockout games than Kane.
