Tottenham Hotspur 6 Millwall 0

A hat-trick from Heung-Min Son sent Tottenham cruising past League One Millwall and into the last four of the FA Cup in the last-ever tie to be played at White Hart Lane.

Christian Eriksen opened the floodgates with an excellent finish of his own, after replacing the injured Harry Kane in the opening minutes, and Vincent Janssen claimed his first Spurs goal from open play as a late substitute.

And Mauricio Pochettino’s men will hope to banish their Europa League demons when they return to Wembley next month alongside fellow semi-finalists Arsenal, Manchester City and the winner of Monday’s tie between Chelsea and Manchester United.

Millwall arrived as the only side in the Premier or Football League not to have lost in 2017, with their unbeaten run stretching over 17 matches.

But Spurs, unbeaten at White Hart Lane since last May and with four changes to their starting line-up from the win over Everton a week earlier, were quickly into their stride, dominating possession in the opening minutes.

Son and Harry Winks both forced Tom King to make save, while Kane also saw a well-struck effort from an acute angle blocked at his near post by Millwall’s deputy keeper.

But Kane fell awkwardly, with his ankle twisting under the body of defender Jake Cooper, and could play no further part in the tie.

Pochettino sent Eriksen on in his place, keeping Vincent Janssen on the bench, and the hosts had shouts for a penalty turned down when Dele Alli’s shirt was pulled in the box.

Millwall broke out for a rare sight of Michel Vorm’s goal midway through the half, but Steve Morison sent his 25-yard effort wide of the far post.

And Spurs got their noses in front moments later when a ball into the Millwall box was headed upwards by a visiting defender and when it cushioned off the chest of Alli, Eriksen pounced to steer a volley on the turn beyond the dive of King and into the far corner.

Victor Wanyama sent a header against the crossbar from a corner, but it was 2-0 four minutes before the break when the ball was moved to the right wing to Son who, after getting it stuck in his feet, checked inside and curled a delightful left-footed effort past poor King.

And Spurs showed no sign of letting up after the restart, with Ben Davies dragging a shot wide within four minutes and Eriksen testing King with another full-blooded drive before the third goal arrived in the 54th minute.

It was simple in one sense, in that Kieran Trippier played a long ball over the top of the Millwall defence for Son, but superb in execution as he then watched it drop over his right shoulder and volleyed past King from around 12 yards.

Alli had another penalty claim ignored by referee Martin Atkinson, then dragged a shot wide following a short free-kick from Winks, before Millwall went close to a reply as Jed Wallace fired just over the bar from six yards after good work from substitute Fred Onyedinma.

And Tottenham claimed their fourth when Eriksen collected a pass just inside the box from Trippier and fed the ball across the face of goal for Alli to provide a simple finish at the far post for his 16th of the season.

Alli made way for Janssen moments later, with the Dutch striker potentially looking at getting more playing time in the coming weeks given Kane’s injury-enforced absence, and Wanyama was replaced by Moussa Sissoko a few minutes later.

And Janssen needed just five minutes to make his mark, clipping a first-time shot, left-footed, from Son’s pass into the bottom corner of the net to claim his first goal for the club from open play, having netted four penalties to date.

His team-mates were quick to join him in celebration, but Janssen should have had another on 83 minutes when Jan Vertonghen’s superb cross picked him out for a close-range header, which he sent straight at King.

The hosts kept pushing and Winks flashed a left-footed effort past the post as normal time drew to a close, before Eriksen clipped a cross in from the left wing and Son’s left-footed volley was fumbled through his legs by the unfortunate King.
