Is "home goal" an eggcorn of "own goal"?
The Eggcorn Hunt Club thinks so, but concludes:
It's difficult to Google for other examples of this eggcorn, since 'home goal' has at least two non-eggcorned senses as well: a goal scored by a player at their team's home ground, and a small goal designed for use in the garden of one's home. "home goal" on Google gets about 108,000 ghits, and the first hundred all seem to be examples of one of these two non-eggcorned senses.
Ngram suggests "own goal" antedates "home goal".
Reports containing home goal usually refer to a goal scored at the home ground. But you can find examples of both used in the same newspaper report.
For example, a headline says "Another home goal for Newcastle owner", and the article says "Football shirt-wearing Newcastle United owner Mike Ashley scored another own goal in the City yesterday." Normally reporters don't write headlines; it's possible the copy/sub-editor got it wrong.
So in general, yes, home goal is an eggcorn for own goal, if it means a player scores a goal against his own team.
