Barcelona defender Gerard Pique is eagerly anticipating the Champions League quarter-final tie against AC Milan, and has labelled the encounter \'a great tie between two big sides\'. The clubs have already met in this season\'s competition, having faced off in the group stages of the tournament. Milan held Pep Guardiola\'s men to a 2-2 draw at Camp Nou, before the Catalans defeated the Serie A champions 3-2 at San Siro in the second game. \"Milan v FC Barcelona in the quarter-finals of the Champions League!! A great tie between two big sides!\" stated the Spain international via Twitter. Meanwhile, versatile Milan midfielder Urby Emanuelson seemed to be less than pleased to be paired with the Champions League holders. \"Barca again ...\" was the Netherlands international\'s short yet telling reaction via the social networking site. The first leg of the Champions League quarter-final will take place at San Siro on March 27 or 28.
