Chelsea were celebrating after John Terry's red card against Manchester City was overturned but Luiz Felipe Scolari was far from happy with his side's performance against Bordeaux.
Despite the 4-0 scoreline at Stamford Bridge in his first Champions League match, Scolari felt there was plenty of room for improvement.
''We know that we made many mistakes in the second half,'' said the Brazilian.
''We tried to attack without the ball and with no good connections. But most important for us is the result.
''It is important to start with a win because in this competition you never know what will happen.
''You see that Cluj beat Roma. That is a warning for us for the next game. ''It is important to win and if you play well that is better, but today we did not play every well.
''They make many mistakes when they have the ball. When you play in the Champions League and are winning 2-0 at half-time you need to work the ball and control the game. You don't need to win 5-0, it is still the same three points.''
Rare headed goals from Frank Lampard and Joe Cole put Chelsea in control of the Group A opener, then Florent Malouda and Nicolas Anelka added late strikes.
The result, if not the performance in Scolari's eyes, capped off a pleasing day for Chelsea after the decision of the Football Association's independent regulatory commission to clear Terry.
Scolari said: ''I am satisfied because it is the first time I am a coach when they changed the decision of the referee.
''I think only in England this would happen. In other countries the referee is the God.
''This time the referee said he made a mistake. For me it is a surprise, a positive surprise. The Football Association understand that the referee makes mistakes sometimes like you and me.''
His attitude contrasted with the anger of Manchester United boss Sir Alex Ferguson who claimed a Manchester United player in the same situation would not have been so fortunate.
However, Scolari refused to be drawn, saying: ''I don't speak about Manchester United, I speak about Bordeaux.''
Bordeaux coach Laurent Blanc, a World Cup-winning centre-back with France, was left to rue his side's poor defending.
He said: ''When you look back and analyse the match you have to say we were up against a superior team but we showed them too much respect.
''Maybe we held back a little bit. We weren't aggressive enough. The scoreline says it all.
''When you fight as hard as we did to get in the competition you have to give more in terms of effort and commitment.
''We could have done more and given a better account of ourselves.''
