Beto has his own number but is our defacto No.9*
* in 'old money' as it were
We Tend to fixate only on the successful No9s while forgetting the many many failures.
A Peak Yak or Lukaku could wear 69 for all I care.
iirc, Lukaku picked his own number and, in the 'modern' manner which thinks that the No10 is the top dog, not unsurprisingly, didn't give 9 a glance and went straight for No10.
If somebody scores 20 goals this coming season who cares what number he has on his back
It's the badge on the front that matters
