Tottenham booked a place in the EFL Cup final as Moussa Sissoko and Son Heung-min got the goals in a 2-0 victory over Brentford.

Thomas Frank's Championship promotion-chasers headed into the match bolstered by a 16-match unbeaten run and victories over four other Premier League sides in this season's competition, but Sissoko's 12th-minute header punctured any early enthusiasm.

The visitors posed enough questions of Spurs in their usual eloquent style and Ivan Toney had a 63rd-minute header disallowed for offside.

Son then streaked clear of their defence to hammer home his 16th goal of the season and grant Tottenham boss Jose Mourinho his latest shot at silverware.

Brentford finshed with 10 men after Josh Dasilva's ugly lunge caught Pierre-Emile Hojbjerg.

They had given themselves an uphill task by allowing Sissoko far too much room to glance home Sergio Reguilon's left-wing cross in a first half of few chances.

Toney outmuscled Davinson Sanchez to get on the end of Bryan Mbeumo's floated 34th-minute delivery, although Hugo Lloris was equal to a looping header.

The Brentford striker arguably caused his own goalkeeper more discomfort when Lucas Moura's header from Son's corner spun off Toney, with David Raya saving superbly as he tumbled backwards to his left.

Serge Aurier made a vital last-ditch challenge to thwart Toney after Mbeumo got the better of Sanchez five minutes into the second half.

Aurier and Son spurned presentable chances and Toney thought he had equalised for Brentford, only for a VAR review to show he was fractionally offside.

That close shave roused Spurs from their second-half torpor and Harry Kane combined with Tanguy Ndombele for the latter to slide Son through for an emphatic finish.

A spirited Brentford were sapped by that strike and needed another impressive intervention from Raya to prevent Kane from adding further gloss to the scoreline.

Dasilva was deservedly dismissed six minutes from time after leaving Hojbjerg with an ugly gash on his shin.

What does it mean? Mourinho's League Cup love affair continues

Mourinho has lifted the three-handled trophy on four occasions and it was his first honour in English football with Chelsea back in 2005. It was also the last major prize Spurs were able to collect, back in 2008. Victory over either of the other semi-final combatants - his former club Manchester United or Pep Guardiola and holders Manchester City - would surely by richly enjoyed by Mourinho if he and his players can complete the job at Wembley in April.

What's next?

Both sides turn their attention towards the FA Cup this weekend, with Brentford hosting Championship counterparts Middlesbrough and Spurs travelling to non-league Marine in the most intriguing tie of the third round.

Son Heung-min scored his 100th goal for Tottenham in all competitions as he netted against Leeds United, with Harry Kane the provider once again.

The South Korea forward, who moved to north London in 2015, has been in sensational form in 2020-21, and moved onto 99 Spurs goals with a cool finish on the break at Liverpool in December.

Son drew a blank in his next three outings, failing to find the target as Spurs went down 2-0 to Leicester City, before he had a goal disallowed in an EFL Cup win at Stoke City and then only managed one attempt at goal in a 1-1 draw with Wolves on December 27.

However, after Wednesday's scheduled game with Fulham was postponed, his landmark effort came against Leeds on Saturday.

Kane – who has now assisted nine of Son's 12 Premier League goals this term – whipped in a brilliant cross from the right, which his strike partner swept home first time.

Son's strike put Spurs 2-0 up just before half-time, with Kane's penalty having put Jose Mourinho's men ahead.

With 169 goals to his name, Kane is the only Spurs payer to have netted more goals than Son since September 2015.

It was also the 13th time Kane and Son have combined for a goal this season, which is a joint-record in a single Premier League campaign.

Son has scored 65 of his 100 Spurs goals in the Premier League – 35 coming from his right foot, 25 from his left, and the remainder with his head.

The former Bayer Leverkusen forward has also supplemented that tally with a further 33 assists, while he has scored 15 times in the FA Cup and EFL Cup.
