Sheffield United boss Chris Wilder says they cannot afford a slow start at Chelsea today.
Wilder recalled their 2-2 draw three years ago, where they fought back from 2-0 down after freezing early in the game.
"I have talked about it but I have said to them I know, there are times when stuff is relevant and I do believe that day was ... a first big away day in the Premier League against a top four club and for 45 minutes we just stood there in their shadows and were starstruck by them," Wilder recalls.
"I think we were swapping shirts and signing autograph books, we just took a step off them and got caught up in all that, which you can do when you are traveling down the King's Road and you step into Stamford Bridge and you see everything that is connected with that football club.
"There's a group of players there we talked to at half time that we needed to be us and we did and we got a great start to the second half and we were really competitive and I believe it did us the world of good in terms of getting that result. It felt like a win and I'm sure any result will feel like a win on Saturday afternoon."
