Real Madrid are supposedly willing to let Bale go on a free transfer.

Simple.
Offer him a ｣50000 per week which would be part funded from extra season ticket sales, merchandising and hopefully the success that he would be able to bring.

And offer him equity. The value of the stock was declining and now more rapidly. The potential share gains are lost unless something dramatic happens to push it back up again.

Have there been any other player owners? Is it allowed?

Many will say that he won稚 come back. Fact or opinion?
