Ernesto Valverde insisted he was not concerned after Barcelona failed to score in a Champions League group stage game for the first time in five years.
A goalless draw against Olympiacos kept Barca waiting to confirm progression out of Group D.
Victory in Greece would have booked Barca's passage to the knockout phase, but the three points proved elusive on a night when Luis Suarez hitting the top of the crossbar was as close as the visitors came to scoring.

Despite his side's failure to score - and win - Barca boss Ernesto Valverde was unconcerned
Barca last failed to find the net at this stage of the competition against Benfica in December 2012, but Valverde is relaxed with his team still three points clear.
'(Olympiacos) have done a great defensive job and were looking for a surprise on the counter-attack,' Valverde said in comments published on the club's website.
'We have taken a step forward even if we have not obtained the result we were looking for to make sure of qualification.
'I do not worry about the lack of goals because we created chances and sooner or later the goals will come.'
