The former Barcelona midfielder said: "I was actually inside the Nou Camp when Manchester United beat Bayern Munich to win the UEFA Champions League in 1999. I got tickets along with a few friends and it was an amazing experience. I like them as a team.
"They have good players but we can do well against them. I know that there will be a lot of interest in the match because it's the champions of Scotland and England playing each other. But we are not thinking about the game like that. We just know that we need a good result to keep up our dream of going further in the UEFA Champions League."
