Rumours about CR7 didn't stop since the beginning of the season and it was obvious that he won't stay for long there.
Until now there is 2 options: whether he join Chelsea or Saudi Arabia.
For Chelsea, Pro: playing in Champions League ; Con: less money.
For Saudi Arabia: Pro: less hassle, moar moneh ; Con: where am I? no more important games and competitions. His records will stop.
There is option 3 that doesn't make sense after Saudi offers which is USA.
Option 4: home sweet home but what's the point now? He can return after a year or two.
