Just had a look at the match replay. Strange how thinking back I was convinced it was a tackle that brought Young down but actually as he just got ahead of the defender the defender put a bit of an arm out and I reckon Young went down a bit easily.
Haven't watched any of it back yet but he's on a hat-trick and through on goal, there's no reason to go down if you're on as hot a streak as he is. Ultimately, nevermind as we won I guess.
