Jose Mourinho moved Tottenham Hotspur to within one game of their first trophy in 13 years as they earned a Carabao Cup semi-final win over Brentford.

Spurs have not claimed silverware since they beat Chelsea in the 2008 League Cup final and they were made to work hard before seeing off the Championship promotion chasers in this one-leg semi-final at Tottenham Hotspur Stadium.

Brentford had beaten four Premier League sides in the run to their first major semi-final but they were behind after only 12 minutes when Moussa Sissoko headed Sergio Reguilon's cross beyond Bees' keeper David Raya.

Thomas Frank's side thought they had equalised after the hour when top scorer Ivan Toney headed in but the goal was ruled out for the most marginal of offsides when the striker was actually down on his haunches earlier in the move.

Spurs increased Brentford's sense of injustice when Son Heung-min raced clear to add a second after 70 minutes before the visitors were reduced to 10 men following Josh Dasilva's foul on Pierre-Emile Hojbjerg.

Mourinho's side will now meet either Manchester United or Manchester City the final at Wembley in April.
