Breen even pointed this out himself before the start of the season. (That it's maybe not so good idea he is the only experienced driver).
As correctly pointed out this seems aimed at Ford or Redbull to give them more money.
The number of experienced and (at least partially) available drivers is quite limited though: Mikkelsen then maybe Østberg and a distant Paddon (unlikely due to Hyundai links) or Meeke (unlikely due to possible car repair costs). They kicked Suninen, so don't see them calling him.
Anyway, talking about possible solutions, they could offer something like zero salary up front and big bonuses for results/podium. But that still needs them having some money to run the car and someone else to play those bonuses if results come.
