Chelsea winger Willian was obviously quite disappointed with the Blues’ 3-0 defeat against Barcelona at the Camp Nou last night.

Knocked out of the Champions League’s round-of-16, the 29-year-old has spoken to the Brazilian media after the loss, and claimed that it was Chelsea’s own mistakes which made the result as it was.

“We worked all week thinking about making a good game,” Willian told TV channel Globo.

“As I said there in the press conference, we had to make a perfect game, without errors. And with two minutes we ended up making a mistake and conceding a goal.”

The player doesn’t think Chelsea did bad offensively, even though they obviously didn’t convert the many chances they created in the game: “In the first and second half, the team did well. We created several chances, we could have scored.”

Speaking of the best player on the planet, Willian also thinks the Blues should have been more cautious regarding Lionel Messi.

“Yes, yes, we knew that. That’s why I ended up saying we could not make any kind of mistake. We know, we knew of the quality that was on the other side: Messi, Suárez, Iniesta, players that in an error, they can decide.”

Out of the Champions League, Chelsea now prepare to face Leicester City in the FA Cup on Sunday.

The battle for the Premier League’s top four continues only after the international break, with a London derby against Tottenham Hotspur at Stamford Bridge.
