I would love to sign him. Mainly because the bosnian is more of a natural playmaker who can play deeper if needed, the type we need. But Pjanic plays in provincial Roma, dont forget that. Having your best season at 26 after being inconsistent for most of your career prior (he was amazing in Lyon, thought he would be better then he turned out) and Götze struggling in a big club like Bayern doesnt say much about overall quality, especially since the latter has been title winning impact player who been great in CL for Dortmund and decided World cup at his age already. Struggling but not out, Pjanic has had a better season then Hazard too but it doesnt mean much for assessing the long term quality and career of the players.
We need Pjanic type more then Götze, depending on the formation Allegri goes with. If its our current one, Pjanic is CM and Götze is FW basically. He scored 2 goals as such basically yesterday.
