I think my view was that at a minimum we needed those 4. I'm always for more. :)
That said I get your position on Goalkeeper. I was just saying if we didn't buy one we could always go that route.
I'm not as big on the DM need though. I think we need a concentration of players that can breakdown the opposition not defensive watercarriers. That's what Bakayoko, Fabihno etc are in my eyes.
We'll need that guys in 6 games all season. 3 times on the road in the Prem and 3 times on the road to top European teams at the most. Funny enough, I'd rather just have Dihno or OTamendi play that role in those games. While we stack up on players of Isco, Silva, Gundogan, Debryune and Dahoud type technical capabilities. Not to mention Garcia who I believe is about ready for prime time.
CB depends on Komps, no?
