Think he was always going to have a bit off a drop off. His form when he joined was insane, almost unsustainable. TBH we could also do without drawing early conclusions or unrealistic expectations on new additions. They almost always look world class in the first month. Martial, Rashford, James, Ighalo, Matic, Maguire, AWB, Bailly etc. The law of averages will also meet up with Greenwood at some point. It's partly opponents adjusting to the player and the adrenaline pump of joining a new club wearing off
He's still comfortably an important piece and a threat to create at any point in a match. The results and production speak for itself
