“I know how difficult it is to come to this stadium and secure a good result. Both matches [against Benfica and Real Madrid] are important but the match against Benfica is more important because we have to face them sooner.
"We’ll have enough time to focus on the Clasico," he said.
Finally, the Argentine had words of praise for summer signing Alex Song.
“He’s done a great job in the short time that he’s been here. I’m sure that as time goes on we’ll get to see much more of his qualities.
"He comes from a team that’s managed by a demanding manager, where they employ similar concepts to ours.”
