Willian has revealed Chelsea boss Antonio Conte wanted Chelsea to be compact and play counter-attacking football against Barcelona.
“In a difficult game we played very well,” Willian said.
”We had to stay compact, we had a plan and we did exactly as we expected.
“They had the ball and we expected to counter-attack, and we could win this game. But we did not and the result is still open, we have to go there and try to win.
“Barcelona had more possession but they did not create more dangerous chances to score. We can go there and make the game.
“To play in the Nou Camp is totally different and we have go there with the same mentality and try to win the game.
“We were good, we played very well but we made a mistake and then we suffered a goal – but we can go to Barcelona and do a good job again.”
