Given Tottenham failed to qualify from a seemingly easier Champions League group last season, they looked to be up against it after being placed alongside Real Madrid and Borussia Dortmund this time.
Yet they have made remarkably light work of that challenge, not only reaching the knockout stages but securing the top spot with a game to spare.
Spurs needed to match Madrid's result on Tuesday to claim first place, and they faced an uphill challenge at half-time, trailing 1-0 to Dortmund in Germany while Real were cruising to a 6-0 victory over Apoel Nicosia.
But Harry Kane levelled after the break and Son Heung-min then struck, too, ensuring the North Londoners also claimed three points and cannot be caught.
