If Bale moves to Internazionale I believe that we would be entitled to solidarity payment according to FIFA-rules.
Solidarity Contribution - Payment breakdown
When a professional moves during the course of a contract, 5% of any compensation, with the exception of Training Compensation, paid to his Former Club shall be deducted from the total amount of this compensation and distributed by the New Club as a solidarity contribution to the club(s) involved in his training and education over the years (calculated pro rata if less than one year) he was registered with the relevant club(s) between the Seasons of his 12th and 23rd birthdays, as follows:
Season of 12th birthday: 5%
Season of 13th birthday: 5%
Season of 14th birthday: 5%
Season of 15th birthday: 5%
Season of 16th birthday: 10%
Season of 17th birthday: 10%
Season of 18h birthday: 10%

Season of 20th birthday: 10%
Season of 21st birthday: 10%
