I would defer to one of the United fans here but I think he is probably still behind like Elanga so at best he is probably fourth choice; Behind him, Sancho and Rashford at best. There is definitely a path to minutes though; Ronnie leaving would wrong help him get in the 18 regularly.
Yeah I'd say Elanga is ahead going into this season. Garnacho went on tour but didn't play any minutes whereas Elanga played in every game.
Garnacho's performance against Rayo was better than anything Elanga has shown in preseason so it could change.
