The Tottenham Hotspur defender has been discussing the simple key to success against Jose Mourinho's men.
And Rose says it is amazing what confidence did for Tottenham on the day, as the north London side would have 'crumbled' in the past.
“It’s amazing what a bit of confidence can do, especially after going 1-0 behind," the 24-year-old is quoted as saying by the Daily Mirror.
“In the past when Tottenham have gone 1-0 behind to bigger teams, we have sometimes crumbled. But we showed great character against Chelsea on Thursday.
“People say they never saw that result coming and, after the first goal, neither did I. It looked like it was going to be a long evening.
“But it shows how far we have come from a couple of months ago when we were winning one and losing one – especially at home when we were struggling against so-called lesser teams."
