It's not even a "who does he think he is" for me. Can you see the likes of Messi or Zidane doing something like this? To me it makes him look a very immature, attention seeking bellend, regardless of whether he manages to fulfil his (alledged) massive talent.
theres that but hell it would almost be understandable if a Zidane or Messi did it (no one would be surprised if Ronaldo did it)
