Yeah but the problem is to fit them all. It's one of Cavani or Ronaldo and he doesn't like to be subbed.
Cavani didn't sign for warming the bench either.
He didn't sign to be a sub last year either and liked it enough to extend his stay. They're both mid thirties and would probably benefit from managing their minutes for maximum effectiveness, so one getting subbed on from time to time would work in our favor.
