With Willian's 25th-minute deflection being boosted by a Martin Kelly own goal, Chelsea then failed to score for the remainder of the fixture.
Prediction: Barcelona versus Chelsea at Camp Nou is a hard match to predict, notwithstanding the fact that Barcelona remain favourites in the game.
The sides were locked together at 1-1 after Messi's equaliser in the first leg of the last-16 tie at Stamford Bridge and Antonio Conte's men held their own for long periods once again, only to be undermined by uncharacteristic defensive errors. However, David Luiz and Ross Barkley are still out injured and will not be able to play in this game.
Barcelona did not make an attempt from range in the first leg because they wanted to break into the stubborn Chelsea defence.
With half the Chelsea side closing in on him as he collected the ball just inside the D, Ronaldinho stuttered on the spot before poking a right-footed shot through the slenderest of gaps and past Petr Cech.

"We have to pay special attention to him, but [also Alvaro] Morata, Pedro or Hazard". If you play against Barcelona, to have opportunities you must be ideal.
"He is a possible starter for our match (at the Camp Nou) and he is showing a lot of focus and is fighting for his place".
The pressure will be much on the visitors to score and Barcelona can punish the Blues if they find an opening.
Chelsea are likely to be without defender David Luiz, who is recovering from an ankle injury, while Ross Barkley remains sidelined with a hamstring issue.
"For me, Messi is the best player in the world and in history". He scored three goals. We are playing against a very good team with a defensive play.
Of course, why change a winning formula at this stage of the competition, especially in a game where you want to avoid conceding.
