He's looked decent when he's started games as well it just hasn't happened very often. He's a better option than either Deulofeu in the front 3 or Rakitic in the midfield in my opinion. He probably won't cut it as a Barca player but based on our current options I'd be playing him more.
Then he has a bad game against half decent opposition and its back to "Deulofeu is much better".
