Thanks Dave and I agree with a lot of that.
I would say that teaching someone creativity, vision and technique to strike a ball as he does with his left foot is a lot harder than teaching someone how to recover defensive shape or how to press to a solid level. There will be players who excel in this (McCarthy and Sigurdsson are both very good at it). He runs with his head up as well which is a big plus. I think Silva can see these attributes and the fact he's signed a Contract suggest he feels quite content with his lot currently (which is very little game time). I suspect it means he values the training he's getting.
On what he needs to improve it's a bit of the Ozil V De Bruyne paradigm. He always reminded of Ozil from a teenager and I'm on record as saying as much. De Bruyne a similar player has been a revelation because he's dropped deeper and been able to dictate the flow of a game far more as you generally would when you get the ball deeper. I am not sure if he will go forward and have a focus on being more of a 10, and be judged on assists and goals more, or whether it is better for him to drop deeper and be a player who can dictate the flow of games before linking up. He would need to increase hit fitness levels to do this. I throw De Bruyne in, as a poster here said he resembled the playing profile of De Bruyne very closely. I'd like to see Silva give him a clear goal to focus on and move him in that direction.
I hope it comes off for him. The vision he has, weight of pass and striking power few possess. He is getting to an age and physicality where he can be trained to do enough on the defensive side of the game. He offers the option of making many chances though. A player like Lukaku would have loved to play with him. It's strange though, Osman always went a bit unappreciated and I think Dowell does to as culturally we are not programmed to rate such style of players.
