I don't get all this fast/slow shite.I have often been baffled why some posters call players slow when they are clearly either not slow or run at a good speed for their size.
I expect a smaller Lucas to be faster than Son but that doesn't make Son slow.
You may have given at least a partial explanation. Thanks.
No way is Kulusevski slow.
Some of the best players ever, from Puskas, Greaves, Muller, Lineker, Bobby Moore, Beckenbauer, Pirlo; to name just a few; did not rely on speed (although some were no slouches).
Their greatest asset was vision, seeing the situation, and anticipating what was about to happen before everyone around them. Kane has this in spades
