Why Tanak, very demanding, not so nice guy to be teammate, but super fast and ruthless rally driver would go to M-Sport, considering that M-Sport to has ok speed car, constant reliability issues (most probably bcs of budget restrains), lack of full scale budget to even run PETs...; after his contract ends with Hyundai - ok, possible, just for fun; otherway - no Ford or some other big backing, no Tanak for Malcolm.
