Marc-Andre ter Stegen wants Barcelona to have a team meeting over their poor recent form.

"It is normal [to be angry] ... At least we've got the three points, which is the most important thing. We need to speak about things. We have to do that among ourselves, I'm not going to say (about what) here, it's internal. There's a lot to improve. I would like to speak first with the players that have been on the pitch," said ter Stegen following Barcelona's 2-1 win over Slavia Prague in the Champions League.

Ernesto Valverde gave credit to Barcelona's opponents, but added that his side must score more goals.

"We had chances to score more goals, but they went all at it and squeezed us a lot. You have to know how to play these games. We lacked some composure in the opponent's half. We had clearer chances than they did, but they could have hurt us. They were like wolves."
