Willian says Chelsea must play the “perfect” game to advance to the Champions League quarter-finals at the expense of Barcelona on Wednesday.
The first leg at Stamford Bridge was drawn 1-1, meaning Barca have a crucial away goal – scored by Lionel Messi, his first in nine appearances against the Blues.
A memorable display in adversity at the Nou Camp saw Chelsea advance ahead of Barca in April 2012 and they went on to win the competition. Willian was asked about that 2-2 draw on Tuesday.
“I was watching that game, but for me every game has history,” the Brazilian said.
“This game already is in the past. Tomorrow will be a new history, new game.
“I think for us to go through we have to do a perfect game with the ball and without the ball.
“That’s the most important thing. To go through to the next round we have to do a perfect game tomorrow.”
Chelsea head coach Antonio Conte knows his side must score and “suffer” at the Nou Camp.
“The final result for the first leg gives a greater advantage for Barcelona,” Conte said.
“We must start the game with great concentration, to stay with our heads on the pitch in every moment, to know there will be moments we have to suffer, to be compact.
“And then when you have the ball you must have in your head, your heart, the feeling you have to go to try to take the chance to score.”
The Italian confessed to having sleepless nights ahead of the first leg and called for his players to relish the occasion.
“I think for the manager, for every coach it’s not simple to sleep a lot, especially before this type of game,” the Italian said.
“In this case I think I slept the right (amount).
“But we must be very excited for this type of game. I hope also for my players to have the same excitement.”
Antonio Rudiger is fit to feature after missing last Saturday’s win over Crystal Palace. Chelsea have no fresh injury concerns, Conte said.
