Inter have built plenty of their recent identity around aggressive wing-backs, and Spence looks like a natural fit for that structure.
This is not just a depth signing. At £30m, the expectation will be that he competes hard for regular minutes and develops into a genuine first-team option.
For Tottenham, the transfer reflects squad reality as much as pure talent evaluation.
That final point matters. If Spence settles quickly in Serie A and grows in a high-profile role, Spurs have left themselves a route to benefit again. It is the kind of clause clubs push for when they still believe a player may have another level to reach.
Reports also say Tottenham are unbeaten in pre-season after a 3-0 win over Hoffenheim, so the timing fits a wider sense of squad trimming before the campaign starts. The question now is whether Spurs move again in the market to cover the position differently, or trust the options already in the building.
For Inter, the next storyline is simple: how quickly Spence adapts. For Spurs, attention turns to the season opener at Brentford and whether this sale becomes part of a sharper, leaner squad build.
