I don't know if he actually shaved his hair or not. In that photo he had the caption of something along the lines of "I bought this shirt months ago, everyone get behind the Real Madrid basketball team". So it could be just a photo from the summer. We'll see in training tomorrow.
The date on the TV says 06-02-20... we can't see which year it is. But the fact that it says that it's Wednesday on that date, while it was Thursday this year, that pic is from last year. Also, that look like the last years basketball home jersey. The 13/14 one has dark blue around the arms.
Yeah, he hasn't shaved his hair. That beautiful hair was ever so present in today's training session.
