We don't need be big fans of him, but as short term vet freebies deal in a young team with little funds, Jorginho could be an astute signing. He would suprise some of you who are reacting like he is the worst player. I watch most Arsenal games and he is pretty much almost allways very good for them.
If it was Allegri system I would say no needs more of a battler then organiser. But for a possession based coach like Motta, Jorginho could be quite a dictating stabiliser for them.
