Tottenham Hotspur has moved to within one game of a first trophy in 13 years after securing a semi-final win over Championship side, 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.
Mourinho has won the cup on four occasions and goals from Moussa Sissoko and Son Heung-min ensured he now has the chance to make that five, having become the third manager to reach the final with three different teams.
Brentford had beaten four Premier League sides in a run to their first major semi-final but they were behind after only 12 minutes when Sissoko headed Sergio Reguilon's cross beyond keeper David Raya.
Mourinho's side will now meet either Manchester United or Manchester City in the final at Wembley in April.
