From this article here, it says: 'Hasler says it is important to have the vital one, six, seven and nine positions stable for the two matches. "We will be keen to have Brett Stewart, Jamie Lyon, Matt Orford and Matt Ballin get as much playing time as possible in the London match. They are the key combinations for a good performance," he said.' So I guess that means either Tony Williams or even Bani will get the vacant centre position? Neumann maybe?
