My Spurs supporting mate explained it to me like this, "He might not get the goal or the assist, but he is always involved in whatever lead to a goal or assist. He ties it all together."
Now, do I think we should move Bellingham to accommodate him? Absolutely not. On current form, Bellingham is among the best players on the planet. You play him in whichever position he is most comfortable and most likely to win you games, as he has been doing for Madrid.
