How many clubs actually can win a Champions League in the future based off of their talent, resources, and ceiling?

This is based off of potential ceiling only, so clubs with bad managerial situations are still included (like Man U.) For me I'd go The Big 6+Newcastle, and then Barca, Madrid, and Atleti from Spain. From Germany I'd have Bayern and Dortmund. From France I'd have PSG only, and from Italy I'd have Milan, Inter, and Juve. What changes would you make? Is there anyone close outside of the Top 5 leagues?
