Barcelona is 4-0 ahead of Como in the Joan Gamper Trophy final in full cruise control with a dominant half-time.
La Blaugrana wants to achieve a fourth summer victory to draw before the summer with a victory in the Estadi Johan Cruyff.
Hansi Flick shaken his starting line 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, and he had a hand in the third goal of Barcelona of the first period.
Spain International Fermin Lopez also received a surprise start from Flick and the 22-year-old took the opportunity with both hands.
A defensive error gave him the chance to shoot the first goal of the game home before a creaking long -distance effort doubled the benefit of Barcelona at 35 minutes.
With the hosts in full flight they were able to stretch their legs before the break, to place the game outside Como.
Rashford burst the right channel and his perfect back post was sent home by the wild Raphinha.
A perfect link between two from Flick's starting attack trio and it was more link up play for Barcelona's fourth just before the interval.
Rashford forced more defensive indecision in the backline of Como, while Raphinha goalkeeper Jean Butez defeated a loose to set Lamine Yamal for a short distance slap.
The case for Rashford to replace the wounded Robert Lewandowski next weekend, continues to grow and Flick can rest for the second period to keep the England fresh for the flight to Palma.
Ferran Torres and Gavi will both be looking for playing time in the second half with the first also a candidate to cover for Lewandowski.
