Barcelona defender Gerard Pique admits they're struggling after their 0-0 draw with Champions League opponents Slavia Prague.

The Catalan defender acknowledged that the Blaugrana haven't managed to meet expectations so far this season.

"We are not playing as we want, but in both LaLiga and Champions League we are in a good situation in the table," Pique said.

"The results are not bad, they could be better, but we must keep calm and improve.

"Playing at this level, it is difficult for us to win the Champions League.

"We have had other spells where we were not playing very well, for example under Luis Enrique and then we ended up doing the treble."

Pique broke down the game against the Czechs and insisted that Barcelona need to find a solution to their unconvincing performances in the near future.

"[Slavia] tried to play a game that suited us," he added.

"We have had chances, but the ball didn't want to enter [the goal].

"The results have not helped us out in these last few games, and when you chain two games together without winning at Barcelona, people want more as there are high demands.

"We have to solve this situation as soon as possible and we must have a cool head."
