Fifa 20 career mode and Pro Club scores are gone?

I've put a lot of time into a career lately and that's by far the best of me. Now my problem is that my career is gone. Before the problem I deleted some data on the Ps4 in order to download another game. Could that have something to do with it, you have suggested solutions, thank you in advance.

We don't know exactly what data you deleted. If you've deleted data from the game, don't be surprised if it's gone. But game data doesn't really take up that much memory, so deleting games would make more sense.
