On the 2-1 defeat...          
"Both teams showed great spirit. It is difficult to swallow a defeat like that. It is unfortunate we lost this game, but we are still in the tie. We have a good opportunity to turn it around in the second game. The goals we conceded were difficult to imagine in a Champions League game."

On Porto's second goal...
"What can you do? The backpass was accidental. Where do you see a defender kick the ball back with his toe? It was completely accidental. The ball hit Sol, it was not on purpose and it has to be intentional to be a free-kick. It is difficult to understand how the referee can interpret that or not see that. Then, on an indirect free-kick, if you allow the team to play quickly, just five metres from the goal, how can the team defend that? It is better than a penalty. It was unbelievable that he allowed Porto to play straight away and push the ball into the net.
"I have never seen that and I have been in the game a long time. It is completely inappropriate that he allows that in such a situation. When the referee gives the free-kick he has to allow us a chance to defend it, otherwise it is better to give a goal straight away.
"From a situation where there was no goal chance at all, and no free-kick as well, the referee gives them just a goal. It is difficult to understand, but maybe I am not intelligent enough."

On Lukasz Fabianski's display...
"I do not want to come out individually on Lukasz' performance tonight and judge him in front of everybody. I believe that you have to accept that you lose as a team and win as a team. Any individual performance has not to be analysed publically."

On Tomas Rosicky's penalty claim in the second half...
"I believe there was a strong penalty claim for us on Rosicky which was unfortunately turned down. I feel as well that the repeated fouls in midfield were not punished enough. But Porto played well, and we have a chance to turn things around in the second game. That is what we will try to do, and I am convinced we will do it."

On Sol Campbell's performance...
"He had a decent game. He is disappointed with the second goal but he had a decent game. When you play at this level you do not want to concede goals like that. He scored an important goal which could prove to be vital in qualification. We will give everything in the second game at home. That is all we can do. I am disappointed because we lost the game but we have a good opportunity to do it at home."
