"Porto are a good team and we know our first half performance wasn't good against them, but to get a draw when we went down to 10 men wasn't bad," said Rafa Benitez.
"We made a mistake in our next game against Marseille which was a bad night for us. We need to repair that mistake against Besiktas.
"It's clear we need to go to Istanbul and try to win. If we don't do that we know it will be difficult for us but all we are thinking about is the three points. The players know how important it is for us to win this game."
