I think you're erroneous with that comment, as I did with Bedford.
I also have to say that saying Son needs more 'guile' given the fact he is either usually double-marked or playing through the middle is a very odd statement...unless you want him to go more 'dark arts'?
Here are a couple of pieces to read. Particularly note in The Guardian one to Chris Ramsey.
Factually, it is impossible to say that unequivocally, Son has scored all his goals/made all his assists via one specific repeat action. Especially as he has played under several different managerial styles.
Finally, you simply don't have the career or consistency of goals/assists Son has without being an 'intelligent player' in the true sense of that phrase. 300 PL appearances, 166 wins, 120 goals, and 61 assists doesn't happen without 'football intelligence' or guile..just for fun, his CL record is 55 played, 19 assists and 5 goals, while his FA Cup record is 28 games, 14 goals and 11 assists.
