If Atletico and Juventus pay up what Chelsea are asking, then sure.
At this point in his career, his main concern would be playing time.He could easily use these mid table teams as a stepping stone towards a PSG or a Real Madrid afterall.
If it was a case of Juve bidding some 2-3m less than the other bidding teams than Chelsea would probably reluctantly sell to us cos of the will of the player.
But when you're making poverty loan + option to buy offers,it would be seen as an insult to both player and club.No team is going to accept such conditions especially given it involves a top young talent.
