With the South Korea international's arrival at Tottenham Hotspur, what's their best starting line-up?
GK - Hugo Lloris (No explanation needed here).
LB - Danny Rose Once fully fit, Mauricio Pochettino will likely bring his first-choice left-back from last season back into the fold to replace the unimpressive Ben Davies.
CB - Jan Vertonghen On form, the Belgian makes the side. Although, on current form, Kevin Wimmer should replace him.
CB - Toby Alderweireld The summer signing should hopefully form a strong partnership with Vertonghen, even if they haven't yet.
RB - Kieran Trippier Strong during pre-season, Pochettino should really take the hint and play the Tottenham full-back instead of Kyle Walker.
CM - Eric Dier The 21-year-old has done well so far in central midfield and the form of Nabil Bentaleb and Ryan Mason suggests they aren't up to the task of displacing him.
CM - Dele Alli Very impressive since joining Spurs, while there are very few alternatives.
LW - Heung-Min Son For the money Tottenham paid, the assumption is the South Korean will be a starter.
CAM - Christian Eriksen The north London side need more from the Dane but, at his best, he is easily their most creative player.
RW - Clinton Njie Another summer signing that should slot into the side when fully fit. Alex Pritchard is an alternative, of course, but he could leave on loan, while the jury is still out on Nacer Chadli - who inconsistently produces brilliance in a Tottenham shirt.
CF - Harry Kane (Again, no explanation needed here).
