That's again not what he is saying. It's about quality not financial cost and the two don't always equate as we all should be very aware of by now. Ange clearly understands this and it's why he keeps saying he doesn't care about the financials the CL bring in. It's not going to define his team.
But the financial cost is a fairly good indicator of the quality of the player. You are right, it isn't always but there is a reason the clubs who have spent the most money are generally the ones who win the most trophies.
