Right is playing Kelly instead of Johnson a good idea, yes it is.
Is having Cole Gerrard, Miereles in midfield together a good idea, yes it is.
Is having Kuyt playing anywhere a good idea? probably not but if he is to play anywhere I would rather he plays behind Torres and works his nuts off closing the defenders down.
Finally is it a good idea to play Johnson at right midfield? NO IT BLOODY AINT..! 18 million wasted there, he can`t defend and is only slighlty better going forward, so he shouldn`t be playing anywhere until he learns to defend properly.
