There was controversy over their opening goal, scored by Harry Kane from the penalty spot, after Dele Alli appeared to dive in the box.

Son Heung-min's brilliant acrobatic strike doubled the lead at the end of a first half Spurs totally dominated.

Kane added his second when smashing home Son's unintentional lay-off, before Christian Eriksen nodded home from close range and later drove in his second to further punish the Swans in stoppage time.

Defeat means the Welsh side are bottom of the table after Sunderland's victory at home to Leicester.

Spurs' win - just a second from their past 11 games - keeps Mauricio Pochettino's side in fifth, three points behind fourth-placed Manchester City.
