Alternator belt on citroen c8?

I need to fit a new alternator belt to my 03 plate citroen c8. Its the 2ltr petrol automatic. Belt split 1am new years day. Have ne belt but cann't figure out how to fit. Have removed near-side wheel and stone guard on near-side but was a wee bit shocked and the wheel lay-out. Can anyone direct me to the order on the fly-wheels. Ta.
