"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."
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.

"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."
