London, April 23: England's Football Association on Monday apologised for mocking Tottenham Hotspur forward Harry Kane in a post on its official Twitter account over the weekend. The FA made fun of Kane's failure to score during his side's 1-2 loss to Manchester United in the FA Cup semi-finals on Saturday, reports Efe. The since-deleted tweet asked the question: "What's in your pocket, Chris?" referring to Manchester United defender Chris Smalling, who answered "Harry Kane."
