Midfield is still a concern. Can needs to integrate, and Bentancur needs to elevate his game further and avoid brainfarts/being a card magnet, if we are really serious about winning the CL. Serie A isn't really a concern, but without upgrades in midfield, our journey might end sooner than expected.
Kean looks like he will become a 100 million rated striker in 2-3 seasons. Costa seems to be slowly getting back into form, and Zola's Spinach looks a good prospect.
