The Champions League is finally back.

Barcelona's group opener against Borussia Dortmund at Signal Iduna Park, however, left a lot to be desired.

The two sides played out a 0-0 draw, with the Catalan giants struggling to find a way through against their Bundesliga opponents.

Ernesto Valverde will surely have to go back to the drawing board and make a tweak or two for future fixtures if Barca want to come out of a tough group that also includes Inter Milan and Slavia Prague.

One man, in particular, fluffed his lines in a game where Barca needed him to turn up.

Luis Suarez endured a difficult night, with Valverde's men registering seven shots to Dortmund's 13 and Barcelona's number nine failing to make any sort of impact.

Suarez had 70.4% passing accuracy on the night, attempting only 27 passes and registering just 41 touches during the game.

Only four players had fewer touches and two of them were substitutes. Another was Jordi Alba, who was injured before half-time and the final player was the goalkeeper, Marc-Andre ter Stegen.

His passing accuracy was the worst in the whole team and he also had second-most unsuccessful touches within the Blaugrana ranks - three to his name.

When we factor in that he also had only one shot on target and three overall throughout the game, it becomes much clearer that his performance was not at the required standard.

Valverde will now have to decide whether the 32-year-old remains the right man for the job or whether a change is needed. Only time will tell.
