Arsenal missed out on Champions League qualification for a sixth successive season despite a comfortable win over Everton on the final day.
The Gunners needed to defeat Frank Lampard’s side and hope Tottenham would lose at already relegated Norwich, but with Spurs winning 5-0 at Carrow Road theirs was a forlorn task.
Spurs needed just a draw to seal a top-four finish, but ensured victory in stress-free fashion after first-half goals from Dejan Kulusevski and Harry Kane quickly dispelled any pre-match nerves among the travelling supporters.
Kulusevski added a third with a brilliant left-footed strike on 64 minutes before Son scored twice to give him a share of the Golden Boot, putting him level with Liverpool’s Mohamed Salah on 23 goals apiece.
Spurs finished two points clear of Arsenal, whose victory over Everton ultimately proved inconsequential for European qualification.
Tottenham’s return to the Champions League comes after a two-year absence, having participated in the Europa League and Europa Conference League in recent seasons.
