Top of the group but with too many questions Barcelona Yet to convince in Europe

Barcelona lead their Champions League group with seven points from their opening three games, an impressive tally having taken on Borussia Dortmund and Slavia Prague on the road as well as hosting Inter.

It should be a reason to rejoice, but the reality isn't so positive. The Catalans have suffered a lot in each of their European fixtures so far, and they've looked troubled.

Marc-Andre ter Stegen has been their saviour in the three games, by far being their best player and making big saves to earn them the points.

No control

It happened in Dortmund, at home to Inter and in Prague. Barcelona aren't controlling the games as they'd like, and their midfield aren't dominating the ball.

Physically inferior

Barcelona are being outrun by their opposition. Inter ran 10 kilometres more, while Slavia ran 16 more.

Lacking leadership

In moments of anxiety, they don't have a Carles Puyol figure to pull things together. Nobody has taken over from him, as was seen in Prague.

No solutions from the bench

Ernesto Valverde can't find solutions. Something isn't working and Ter Stegen's comments prove there's a problem.

Lack of goals

Luis Suarez can't score away from home and aside from Lionel Messi, they're struggling.
