As I said previously people have been creaming themselves over James despite his lack of end product whereas Greenwood presents a strong case for a good alternative as he's exceptional in that very important area.
I wouldn't be too harsh on James to say he lacked end product. He can score when playing from the left, which allows him the chance to cut into his right leg. I admit he needs to improve in the final third but I also bear in mind where he was when he first came to the club. What I think he, as well as Rashford and in fact many in the team need, is proper coaching. A good player can have a couple average games and it can be beneficial not to keep trying too hard but sit back and access the situation. I see him and Rashford, especially the latter try to use the tactics that work against an "open defence" (e.g vs Man City or Spurs) on a team that's dug deep. I believe some of the players should be experienced enough not to keep running at such a defence but the coaching crew should be doing a lot more.
It's good to see Greenwood gradually getting into men football. That's how you use a kid. Play them in their natural positions and with the best team you can afford. In that way they get protected, their confidence and invariably play will naturally improve with time. I have seen enough of Greenwood at the youth level to believe he is bound for the top, and this opinion did not change after the first games in which he was average to poor. Read a few criticism about his play and the misplaced trust in youth by some people here. We need patience with kids, and right now I believe we have to use them more. For two reasons. First this season is a write off in my opinion. There is no chance of a top four finish except if we get 3 key players and even at that they may not have the time to adjust before the season ends. The second reason is that the older players we have are not really better. In fact they can be worse some times. It's better to give the likes of Greenwood a significant part of the minutes that have gone to Lingard, Mata, etc. I don't have anything against the two but there is no more room for them to improve beyond their best days.
I have said it before, and maybe will be proven wrong in the future but I believe in Greenwood, Garner, Gomes, Levitt, Aidan Barlow, Laird and Williams. They don't necessarily have to end up as world class players but anything from very good to good is enough. Levitt, Barlow and Gomes may have some question marks, especially the last two but the reason I think they'll make it is their level of footballing intelligence. Or willingness to apply intelligence. Garner is also another intelligent operator. How I wish our own Nani applied a bit of intelligence to his play, he would have been a much better player.
Hoping to see more of Greenwood in the new year!
