Barcelona has clicked into form at just the right time, according to striker Pedro Rodriguez, but he feels the team needs to be wary of an AC Milan away goal in Tuesday's Champions League clash.

The reigning champion did not have it all its own way in the first leg of its quarterfinal tie at the San Siro last week, where a defensively strong performance from Milan kept Barca's prolific forward line at bay and the match ended 0-0.

It guarantees a highly charged Nou Camp for the second leg, where Barcelona is the favorite having already finished above the current Serie A leaders in the group stage of the competition.
