Sending him on loan is a silly idea true, but at what point will he get a consistant run of games playing upfront is my worry, he's not displacing Lukaku anytime soon, Martial is, in my opinion, ahead in terms of talent and ability, Sanchez should really be an automatic starter at this point unless his form falls off a cliff, Lingard is playing the better football.
The only way i see him getting consistant, non bit part football especially in his apparent preferred position, is major injuries to our key players. You' have to assume Ibra is gone in the summer, possibly even Mata, and then I wonder if we will also bring in another attacking player to cover those 2 losses.
