Well,they must be pretty stupid!Let's fleece them some more,and get some real good $$$ off them,while providing them less exposure.I can't imagine AON saying to Man Utd,"we'll sponsor you,but you can have a different sponsor for (eg)local derbies,and we'll let you sell out of your previous sponsor's jumpers before you sell ours".Maybe this is why we couldn't attract a major domestic sponsor!
