The competition was Jose Mourinho’s first piece of silverware 10 years ago and prompted a period of dominance under the Portuguese manager 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 2004/5 season, it had a huge impact on our confidence and momentum.”
