Despite a zero number, FC Barcelona is undeterred towards winning its 27th Spanish championship.
After the 0-0 draw against FC Girona on Easter Monday, Barca are 13 points clear of arch-rivals Real Madrid with ten games to go before the end of the season.
The Royals surprisingly failed in the home game against FC Villarreal (2: 3) on Saturday.
Barcelona found it difficult against the attentively defending guests. Former Bayern striker Robert Lewandowski played inconspicuously.
National goalkeeper Marc-Andre ter Stegen has only conceded nine goals in 28 league games after the goalless draw.
