Kalle would make so much sense running in a pressure free 4th car, and Toyota could have kept Meeke/ Latvala or signed Mikkelsen etc, but the problem is Katsuta. He's Japanese and by all accounts will run in a 4th Yaris for most of the season, so Toyota running 5 cars is probably just too much of a stretch. (Unless fingers crossed, the Redbull millions could be put to additional good use).
