Anthony is a different kind of wide-player to the old-school wingers we have become used to at United.
Of course his numbers for goals/assists could improve but the reason I dismiss 'assists' as a metric (or don't put much weight behind it) is because an 'assist' is just the last player to touch the ball before a teammate scores a goal, it doesn't tell the story of how many goals players help create with other actions.
Extreme example but a player could run 60 yards, beat eight players, roll it sideways to a player who miscues a shot into the path of the goalscorer and it's THAT player then who gets the assist.
When I watch Anthony I see loads of good qualities. He is skilful, the opposition usually double-up or at least commit a player to mark him tightly, he works hard, he is tenacious, he can play in tight areas. Plus, for all the criticisms of his output, the goals he has scored have tended to be important goals. Let's say he had padded out his eight goals with a few tap-ins in games we had won easily...suddenly he's into double-figures and people aren't so quick to write him off based on one metric.
He's still young and learning but I have seen a big improvement in the last 3-months and I personally think the goals and assists will come in time, and with a functioning CF
