He was late, he’s been dealt with, that’s enough, no need to make a big deal.
Unfortunately I don't agree with this. First, it happened twice. Second, I don't think that's the only issue, as I would have expected an internal fine to sort the situation, because dropping him brings a relatively minor thing into the public in a big way (which is why we're discussing it).
I have a feeling, unfortunately, that there's a pretty big problem with his attitude off the pitch and we're not hearing the full story. Which is extremely unfortunate.
Yes, he's young and needs time, but if he's not doing the basics of being a professional footballer then he's not going to come good.
