Luis Suarez has refused to accept that Barcelona are in the driving seat after they beat Paris Saint-Germain 3-1 in the Champions League quarter-final first leg on Wednesday.
The Uruguayan struck a brace to add to Neymar's opener, before Gregory van der Wiel netted for the Ligue 1 champions at Parc des Princes, but Suarez is wary of the threat that Laurent Blanc's side still pose ahead of the second leg.
The ex-Liverpool forward told Sky Sports News: "We knew before the game if didn't concentrate then we couldn't win and in this situation when you play a big team you need to concentrate.
"We know it is an important result, but in football, you never know. There's still 90 minutes more and we need to do it again. I prefer to win the game, and this is more important for myself [than to talk about my goals]."
Elsewhere in Europe's premier competition, Bayern Munich slipped to a 3-1 reverse away to Porto.
