Bayer Leverkusen coach Xabi Alonso must channel the "Miracle of Istanbul", Liverpool's incredible comeback to win the 2005 Champions League final in which he was key, to overcome Bayern Munich on Tuesday.

Bayer Leverkusen's players must be professional and quickly move on from their chastening 3-0 Champions League defeat to Bayern Munich, manager Xabi Alonso said on Friday ahead of a Bundesliga clash with Werder Bremen.

An Architect of the "Miracle in Istanbul" in 2005, Xabi Alonso will need more magic if his Leverkusen are to overturn Bayern's 3-0 aggregate lead.
