Mauricio Pochettino, who took Tottenham to that final in his first season in charge, has turned a young English-spined side into Premier League title contenders yet the suspicion remains they still lack the killer touch required to win trophies.
Antonio Conte's Chelsea have it spades.
Chelsea were outplayed for long periods but struck at the vital moments to claim a 4-2 victory that kept alive their hopes of repeating the double they achieved under Conte's fellow Italian Carlo Ancelotti in 2010.
Tottenham, who twice equalised Willian strikes through Harry Kane and Dele Alli, looked the more likely winners at 2-2 but Chelsea had the luxury of introducing Eden Hazard, Diego Costa and Cesc Fabregas off the bench and it proved decisive.
Hazard fired home after Fabregas's corner was cleared to him before Nemanja Matic thumped home Chelsea's fourth.
A seventh successive FA Cup semi-final defeat sent the Tottenham fans home with a familiar empty feeling, although the club could still be on the verge of something special.
With six games of the season remaining, starting with an away trip to Crystal Palace on Wednesday, Spurs are four points behind Chelsea and still in with a title shot.
