Mason Greenwood had already been a threat at Old Trafford on Sunday, when he latched onto Marcus Rashford's pass and calmly ignored a bellowing Andy Robertson chasing him down to steer a nerveless finish past Alisson for the equaliser.
A cheeky wave to the camera, accompanied by a big grin, was the perfect way of illustrating how the teenager is handling all the attention but it somehow encapsulated just how young he still is. This is a boy still learning his trade who has had to deal with criticism already, much of it unfair when you consider his role in the side has evolved.
