According to CHATGPT his best season is better than the same for Rashford, Luis Diaz or Kvicha when looking at G/A per 90 minutes played.
He also clears them in successful take-ons, ball-carrying and chances created (very close second is Kvicha who is the superior passer and better defensively).
Pretty surprised at how good his offensive output can be, maybe with discipline and a 'carrot'-approach (bigger club, more money, more exposure at Barca, bigger league and competing for big trophies) could see us getting the best out of him?
For a loan with an option to buy or even obligation to buy contingent on some standard performance-based numbers would be a no-brainer.
