Yeah I heard about this a while ago. Personally I think they should have run Liuzzi straight away. Klein never really showed much promise last season and Liuzzi has been very fast in lower catagories. He has already beaten Schumacher of course in a Karting race in Kerpan a few years back.
Changing drivers through a season doesnt work in my view and is more likely to destablise the team more than anything else. When will Jaguar/Red Bull learn?
