(Reuters) - Barcelona are ready for a battle against Paris St Germain in the return leg of their Champions League quarter-final, manager Xavi Hernandez said on Monday, adding that his players are willing to suffer in order to advance.

Barca beat PSG 3-2 in the first leg in France last week but Xavi said his side will need to be nearly flawless to reach the semi-finals for the first time in five years.
