Manchester City goalkeeper Shay Given says they owe their fans a big performance tonight against UEFA Cup opponents FC Copenhagen.
He said: "It was a huge disappointment at Portsmouth for everyone involved with the club. We were not good enough and we need to rectify that.
"Whenever you have a bad performance it is great if the next match comes quickly and you can start to put the record straight.
"Hopefully we can do that on Thursday. We know we let the fans down at Portsmouth when we were not good enough on the day."
Given is relishing the chance to play at this level again after appearing for Newcastle on the continent.
"I have some great memories of European nights and I hope to have some more here this season, " he told the Manchester Evening News.
"It is hard to define but there is definitely a different atmosphere surrounding match nights.
"Sometimes there is not the blood and thunder of the Premier League and it is a little bit more cagey. You find teams want to keep possession more and try to hit you on the break.
"The Premier League tends to be all guns blazing at times but in Europe you have to be tuned in and have a good game-plan.
"We need to put right our away form in the Premier League but I know there has been nothing wrong with it in the UEFA Cup so far."
