Just three days ago, Barcelona were defeated in LaLiga 3-1 with Levante. Barcelona also scored a 0-0 draw with Slavia Prague, the team bottom of the Champions League Group-F point table. Barcelona remain at the top of Group-F even after this match draw. Yet I would say Bercelona's performance in the last 2 games has been very poor. No one expects anything like this to such a good team.
Hopefully Barcelona will return to their old form again soon.
