So the most recent story is from 3 years ago when he was still a 20 year old kid?DT is fair in his assessment of Martial (its far from a hatchet job), saying that he drifts between a 6 and 8 rating but never looks enthusiastic. Recognizes that he has the skills to succeed but questions if he has the drive to push on and consistently give 9/10 performances that the ballon d'or type players do.
Some of the stories mentioned:
Ranieri (who is not known for calling players out) calling out Martial's lack of application while at Monaco
One story about coming on as a sub on 60 mins at Monaco and being subbed off 20 mins later having done nothing
Another about missing a match (away against Norwich 3 years ago) due to a supposed injury but being fine the following Monday for training, resulting in one of the senior players being disgusted and saying Martial 'didn't fancy it'
I'm not saying there isn't any merit to what was said but when then best you can come up with are stories from 3 years ago you have to wonder what exactly the point of the interview was. Certainly a weird time to bring all that up when he's mostly looked good this season when fit and has been scoring and assisting fairly regularly.
