I agree with a lot of what you say but Sigurdsson does work hard in a game, I think Dowell is more creative but less hard working.The irony of the last few pages is that if you want a player who disappears and does little in games other than score then Siggurdson's your man and he pretty much plays every match!
Dowell should be looking at somebody like De Bruyne as a role model, talented ,hard working and always involved in the game. Then again it took De Bruyne a few years to get to that level.
Tho I did forget the other was after he left
