Barcelona goes during the break with a firm 2-0 advantage compared to Como in the Joan Gamper trophy in Catalonia.
La Blaugrana wants to stretch their previous season to four victories and sign for the summer with a victory in the Estadi Johan Cruyff.
Hansi Flick still ties his line -up for the La Liga opener against Mallorca on August 16.
Marcus Rashford has received a first start, on the back of scoring his first club goal in the victory over FC Daegu at the end of July.
Robert Lewandowski's injury has given Rashford a chance to impress, but it is another new face that has made the most important difference.
Flick chose to bring Fermin Lopez to his starting line and the Spain International has seized its chance.
In the first 45 minutes of some clear opportunities, a bad pass of the Como defense was intercepted by Lopez, who shot Jean Butez for 21 minutes.
Sharp anticipation and a composed finish from Lopez will keep him in the mind of Flick for a possible starting place in Palma next weekend.
No.16 from Barcelona was not ready there, because another defensive mix it was from 20 meters of cannons to canon from 20 meters just before the interval.
The majority of the other starters must remain in place with Pau Cubari who cooperates in the central defense.
The main question can focus on Rashford, where Lewandowski will almost certainly miss the first game of the season, and the English international has the chance to leave his mark.
Ferran Torres is only fit enough for a place on the couch and that can play in his favor if Flick stays with the same team at the start of the second period.
