John Terry believes winning the Capital One Cup will give Chelsea a big lift and open the floodgates for more trophies, just as it did in 2005.
The competition was Jose Mourinho's first piece of silverware 10 years ago and prompted a period of dominance under the Portuguese that included a second League Cup, an FA Cup and two Premier League titles.
Terry, Didier Drogba and Petr Cech are the only three players from that squad to have remained at Stamford Bridge and the Blues skipper insists victory against Spurs on Sunday can have a similar effect on the current crop.
"The 2005 win was the first one for the team which made a big impact through all the squad, it set us on our way," Terry said. "It gave us a taste of what we wanted and we wanted it more, I think it brought the squad closer together.
"With that in mind this could be the first one for all of us, the manager is right, we have got to out and win trophies to put us right up there.
"Like everyone I felt something different when the manager came in.
"It was a different mentality, everything was about winning. He made that clear from day one.
"That rippled through the whole squad, through the academy, through the whole club really, and he has continued that, he has brought that back again this time.
"A lot of people write this competition off, but for me it is huge and we look back on that 2004-05 season, it had a huge impact on our confidence and momentum."
Tottenham go into the final at Wembley as underdogs, but Mauricio Pochettino's side can take confidence from their superb 5-3 victory against Chelsea on New Year's Day.
"Everyone is rattling on about that but for me, it was fairly comfortable for us at the Bridge when we won 3-0," Terry said.
"You do get beat throughout the season, it's not our only defeat this season, obviously at the time we were disappointed but you move on and bounce back the following week.
"I don't see it as a revenge thing, 'oh we have to beat them because they beat us 5-3', we also remember we beat them 3-0 and that's football."
Harry Kane scored twice in Tottenham's remarkable win at White Hart Lane and the 21-year-old is likely to be key to Spurs' hopes again this weekend.
Kane now has 24 goals in all competitions this season and six in his last six matches.
"He is a very good player, his movement is fantastic and he is in great goal-scoring form," Terry said. "He has got to be able to do that year after year and for England, I hope he does.
"It is great to see young players coming through and getting their opportunities and staying in the squad so if he keeps scoring there's no reason why he can't stay in."
Kane was rested for Tottenham's 2-0 second-leg defeat against Fiorentina in the Europa League on Thursday night, along with Danny Rose, Kyle Walker, Eric Dier and Ryan Mason.
Chelsea have enjoyed an uninterrupted week of preparation ahead of Sunday's final but Blues defender Gary Cahill does not think Spurs are at a disadvantage.
"I don't think it will make a difference," Cahill said.
"In the finals I've played in, even when I played in the Champions League with some hamstring trouble, it overrides everything in your brain - the tiredness, the fatigue.
"You rule with your heart. I don't think it makes much of an impact.
"Ideally they probably would prefer not to have the Europa League game but a final's a final and those boys will be buzzing for it just like we will be."
