Chelsea were held to a 1-1 draw by Barcelona at Stamford Bridge last night, despite taking the lead through Willian.
A mix-up at the back from Andreas Christensen allowed Lionel Messi to grab an important away goal for the Catalan club – his first against the Blues.
The result means Antonio Conte’s side cannot afford to rest on their laurels in the second leg at the Nou Camp on March 14.
And Eden Hazard has insisted Chelsea have no intention of doing so and will look to attack Barca with the “perfect” game-plan.
“At least we won’t be able to think defensively in the second leg because if we think defensively over there we will be in a lot of danger,” Hazard told the Belgian press.
“We will go there trying to win because we have to score and we will try for the perfect game as we did today except for the small error that we made.
“That’s what made the difference because you’re up against Barcelona.
“Against other teams, perhaps you get away without letting in a goal.
“We played well. We had a plan to defend well but perhaps we could have done more with the ball when we had it.
“But it’s not over. We can still dream. Qualification is still possible.”
And Hazard was also pleased with the way Chelsea managed to contain Barca’s talisman Lionel Messi for much of the game, despite allowing him to score a late equaliser.
“We contained him well today. When he’s outside the box he’s less dangerous than in it,” Hazard added.
“He had one touch in the box today and he scored. That’s the difference he makes.”
