Arsenal boss Arsene Wenger insists they're still in their Champions League tie with Porto.
Despite the 2-1 defeat, Wenger maintains all is not lost in the tie.
"It is unfortunate we lost this game, but we are still in the tie," said the Arsenal boss. "We have a good opportunity to turn it around in the second game.
"There was a strong penalty claim for us on Rosicky which was turned down, and 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."
Wenger added: "Sol Campbell scored an important goal which can prove to be vital now in qualification.
"We will give everything in the second game at home."
