#4. Dan Biggar (Toulon)
The sole representative from Wales in this lineup, Biggar used to bring in a tidy sum of approximately £600,000 while playing for Northampton Saints, following his switch from the Ospreys.
However, he’s now taken his talents across the Channel to the French titans, Toulon, where the word on the street is that he’s pocketing a hefty £800,000.
