Reading between the lines of this quote from a LM interview in the OxfordMail, then I'd say he is a bit too big for his boots around the place and in training, and needs to step it up.
“If somebody’s in credit and you want to force my hand, you have to be an eight or nine every day in training, which Sonny is progressing in those areas.
He’s improving in training but we still want more from him. He’s still going to play a part, it’s just a case of when.
He’s just got to make sure he keeps his head down and keeps working. We support him and brought him in because we know some of the qualities he’s got.
It’s about now making sure that he hits the level in training every day, so when someone’s level drops or there’s an injury, he’s ready to step in and grab the opportunity.”
