Thiago is a central mf, AM type of player.
have never seen him play as a DM
but priorities would be CB and LB.
I understood he was more a defensive than attacking midfielder, but dont remember seeing him play. A CB/LB is definitely a priority together with a CF, Origi is just not good enough
I think he can play deep and is really good at passing the ball long, like Fab & VvD do now, but the question is, if we have VvD & Fab already doing this, do we need another? as has been said, CB & Attacker has to be the priority if we are spending £30+ million, with his age and position, this sounds like Bayern/agents trying to create interest to drive his price up.
