Barcelona manager Xavi has warned his side that they must prepare to face a Real Madrid side out for 'revenge' in the second leg of their Copa del Rey semi-final on Wednesday.
The Blaugrana hold a 1-0 lead from the first leg, having won their third consecutive Clasico, although their performance was not overly convincing and Xavi has already acknowledged that a similar performance will not be acceptable this time around.
Despite their advantageous position, Xavi warned Barcelona that they are not the favourites in a two-legged tie against a Real side with a fierce reputation in knockout football.
