@Hostekule Not many at all, I'm in 2019.
I sold Vietto to City for £37m, he didn't play all that many games in my last season as I tend to play with one up front and I had some incredible regen who took his spot.
Eric Baily is an okay defender playing at Spurs (although only made 6 appearances last season) - I want ones who are very comfortable on the ball so I sold him, and brought in Vallejo who's the same age roughly and much more composed.
Acosta is a nobody, barely getting games for Las Palmas. Sold for £400k and 50% of next transfer fee.
Leiva was a good player for me until he had a hip injury and massively regressed, he's now 1.5* and I rarely play him especially as I just bought Kishna and Cerny.
Gomez was okay, yeah I didn't like his 10 stamina so I sold him to Benfica fairly cheaply. He kept asking for undeserving game time and I got fed up of him eventually.
Costa is now a rotation player at 32, I have Alex Telles ahead of him. He wanted to leave but I asked him to stay and tutor and he did. Although I don't have anybody for him to tutor unfortunately.
I fought tooth and nail to keep both Musachio and Mario, both are at the club. Musacchio is strangely starting to regress at 28 years old, I want to keep him though as he's very good on the ball. Mario is a besat, and is tutoring my 5*PA RB regen.
Trigueros was sold to PSG almost immediately for £25m, couldn't say no at that price.
To answer your question; Mario, Burno, Musacchio, Jaume Costa and that's it.
And just as I type this, City bid for Rulli which I rejected, he then talked to me and I said he wasn't leaving, this pissed off Lucas Romero and Musacchio and they've both asked for transfers. Great.
