Tottenham No2 Gus Poyet admits he and coach Juande Ramos had to lift the players' rock bottom confidence when they first arrived.
Silverware today in the Carling Cup final would represent a remarkable four-month turnaround at White Hart Lane under Ramos, who has altered training regimes and diets to turn results around.
Assistant boss Poyet said: "It's the way you talk to the players, the way you train. You make sure they understand.
"It's easier to convince players when they are winning and easier when you're winning very important games.
"When we came here it was all about how little confidence the team had. Every single game - it was difficult. Now it's possibly the opposite and we are full of confidence. Anything is possible."
Facing his former team adds spice for Poyet, who angered Chelsea fans when he was substituted during their famous win six years ago.
"Even after people starting lying about that and people said on the internet that I kissed the badge and that sort of thing because they wanted to go against me," he added.
"I know what I did and before the game people asked me if I would celebrate if I scored a goal against Chelsea. I said it depends.
"If we were 3-0 down and I made it 3-1 then I won't, but if was a goal that meant we went through to a final after not beating Chelsea for years, how can you not celebrate?
"Me, whenever I scored an important goal I went ballistic, crazy."
