what? Deulofeu at 18 was one of the top scorers of Segunda, he thrived on goalscoring and playing towards the inside. With the B team, his dribbles would often be driving inside even on his right foot. Adama CAN score but that's a secondary aspect of his game as compared to dribbling and crossing.
The only "evidence" for Deulofeu's supposed tendency to only hit the ball forward and cross is his time at Everton which isn't indicative of much. Playing in the chaotic EPL with a targetman like Lukaku in the middle made him play differently than normal. Watch him in any game with Spanish youth or Barca B and it's evident how he doesn't like to isolate himself on the touchline normally.
Also, both are equally selfish I'd say. Adama is almost always either attempting a backpass or taking on 3 players in a dribble and then crossing/occasionally shooting. He doesn't do much in terms of linkup or buildup play. Deulo hasn't either, but it's not like either gets a true edge in that category.
