There is probably never a bad time for a 17-year-old to claim his first goal for Manchester United but, boy, was Ole Gunnar Solskjaer grateful to Mason Greenwood for his moment of inspiration.
This was threatening to become an embarrassing night's work for United against the champions of Kazakhstan, Astana, when Greenwood stepped up, grabbed a limp game by the scuff of its neck and underlined why his manager rates him as one of the most naturally instinctive finishers he has witnessed.
Still 12 days short of his 18th birthday, Greenwood demonstrated the predatory brilliance and cool head of a much more seasoned striker when he shot through the legs of Nenad Eric at Old Trafford for the 1-0 win.
The more skilled forwards make scoring through the legs of goalkeepers a habit and there was nothing fortuitous about Greenwood's aim, just as he demonstrated the enormous benefits of being so two-footed, moving the ball easily from one foot to the next. It makes him hard to read — defenders cannot steer him to a weaker side because he does not have one.
Watch the way Greenwood moves and strikes the ball and it is hard not to think of Robin van Persie. There is a very long way to go before he can lay any sort of genuine comparison to the former United, Arsenal and Holland striker but he has the same sort of peacock strut and gait and strikes the ball in a similar sumptuous, aesthetically arresting way.
