All talents leaving

I am playing in the 3rd - now 2nd, since I just won the league - german league. I have 3 young talents (all having 5 star potential). One is a starter, the other two impact subs and all three are valuable to me. They will win us games in the future. I lost all three. The first was bought by chelsea. I rejected but the board overruled and sold him. The other was unhappy that I rejected a Bundesliga offer. I told him I would sell for 1,8 million (value was 1,2 at that time). Offer came for 1,9 million… Third player. Rejected a dozen transfer offers… and board overruled…
