Ossie Ardiles says Tottenham's future depend on coach Juande Ramos and striker Dimitar Berbatov staying at White Hart Lane.
The Spurs legend told the Sunday Telegraph: "As well as holding on to Berbatov, keeping faith with Ramos is another vital ingredient for building success.
''The vibes are good. I like Jermaine Jenas, for his box-to-box play, and Tom Huddlestone, who reminds me a little of Glenn Hoddle with his range of passing.
"Ramos knows that his side will be underdogs against Chelsea at Wembley, but not massively so. The table doesn't lie and, man for man, Chelsea are the better team. But perhaps the Carling Cup doesn't mean as much to Chelsea as it does to Spurs and that could be a major factor. It will be really close.
"If Spurs can win the final, I really believe that it could be the springboard for future success. The crunch will come next season when people again start talking about the top four."
