Tottenham’s Son Heung-Ming scored four times and Southampton slipped to a 5-2 Premier League defeat at St Mary’s Stadium on Sunday.
Danny Ings gave Southampton a deserved lead that was cancelled out, however, in the closing stages of the first-half when Son began to run rampant against a limp defence.
Harry Kane, who assisted on all four of Son’s goals, added a fifth for Spurs eight minutes from full-time.
Saints were not without chances to build upon their lead or to retake one, but Che Adams failed to convert one his many moments before Son pushed Spurs ahead 2-1.
Ings converted a late penalty as a consolation for Saints, who have lost all three of their games across all competitions to start the 2020/21 campaign, including being bounced from the Carabao Cup by Brentford on Wednesday.
