Yes for me. Kovacic is a decent talent. There's a reason Madrid bought him and Barcelona were in on him.
It's because he's more of a modern CM, Spanish style. Excellent technical ability, quick accurate short passing, good work rate. Versatile in midfield, can play any of the positions basically.
He's not necessarily "eclectic" like Pjanic. But he's a player you need if you want ball possession and build up.
For around 20M you could be looking at adding another building block to our long-term plans (considering he is already comfortable in Italy and Eastern Euro so likely not to run away at first chance).
