Is ‘player power’ in team sports which are currently being bought up by businesses likely to diminish?

Using football (soccer) as my example, players in the biggest (money earning) leagues receive a large weekly wage with smaller bonus sums payable on certain achievements.

As more clubs are purchased by investors and other business-minded people, is this model expected to change in the medium- to long-term?

The current model provides little financial motivation for players to maintain a consistent output, and clubs income is mostly derived from league position and qualification for additional competitions.
