The defeat leaves the Saints 10th in the table and needing an improbable 30 points from the 33 left available to them in their remaining 11 games to match last season's tally of 63. With Chelsea in superb form, this season's title race is unlikely to go as deep into the season as the last campaign, but Tottenham will be hopeful of improving on their third-place finish by at least one spot. Prior to Sunday's match, Spurs had won just three of nine top-flight games without Kane this campaign, during which they had managed just eight goals. However, one of those victories was the impressive 2-0 triumph over Manchester City in October, illustrating that there are goals elsewhere in this talented Spurs side - a fact Eriksen and Alli demonstrated on Sunday with their 10th and 17th goals of the campaign respectively.
Eriksen's strike was powerful, low and accurate to find the bottom corner of Fraser Forster's net after he had collected a pass from Mousa Dembele, while Alli's penalty was efficiently dispatched after he had been fouled in the box by Steven Davis. Spurs boss Mauricio Pochettino had urged summer signing Vincent Janssen to step up in Kane's absence, but opted instead to start Son Heung-min, who scored a hat-trick in last weekend's 6-0 FA Cup win over League One Millwall. The South Korean had two good chances to carry on Kane's good work but failed to convert either as Forster turned away his shot in just the third minute before his sluggishness in the box allowed a tackle to deny him once more. He was replaced by Harry Winks as Spurs were forced into a more conservative approach in the second half, while Janssen was handed a late cameo that saw him draw a good save from Forster with a powerful drive.
Southampton has beaten Tottenham just once in their last nine league meetings and have enjoyed just three victories in 17 Premier League visits to White Hart Lane. Trailing 2-0 at the break, having lost the exciting Gabbiadini during a largely passive first-half display, it looked like being a miserable afternoon all-round for Southampton. However, they came out with renewed vigour and intent in the second half and immediately got themselves back into the game through Ward-Prowse's goal, set up by a low cross from Ryan Bertrand that evaded Jan Vertonghen. Tottenham, though, have conceded just seven goals in 14 matches at White Hart Lane this season and their three-man defence of Vertonghen, Toby Alderweireld and Eric Dier, shielded by the hard-working Victor Wanyama and Dembele, wrestled back control of the game and saw it out. Having lost 4-1 at home to Pochettino's Spurs in December and 3-0 at Ronald Koeman's Everton the following month, Southampton will be glad to see the back of sides managed by their former bosses for this season.
