In the Barcelona attack, 17-year-old will be on the right, and Messi’s position has been played for years.
However, Jamal, who spoke at a press conference on Tuesday, rejected comparisons with his outcome at the La Masia Academy at the club.
“I don’t compare it myself because I don’t compare myself to anyone,” Jamal told reporters.
“I don’t think the comparison has meaning, with Messi less – I enjoy myself, and I’ll be myself.
Jamal is already the European champions with Spain – while making 100 appearances at Barcelona if they play against Inter on Wednesday.
He took another trophy at the weekend, scoring two goals and Barca beat Real Madrid 3-2 in the Real Madrid Cup final.
Barcelona coach Hanse Flick has insisted he could help his side a joy at the Madrid kick.
“At the end of the game, there was a big feeling,” Flick said. “This victory against Real is very important for the positive Vibas, the positive moments, can push you.
Flick said Vorisic Scessen will continue his goal against Inter, despite returning to Mark-Mark-Ter Stegen, the first team after leaving the pitch.
