I think I'm generally agreeing, but my point is that he was a huge prospect as a defender, playing regularly for Anderlecht as a 16 year old.
He was an adequate defensive midfielder, purely a destroyer in that role.
We needed someone who could do that at that time, and you say he couldn't play well, I'm not so sure about that. He wasn't the best, but filled a need and was better than any alternatives we had.
I don't think it was a surprise he got moved back to his natural position. Mancini did some great things for us, but doing this didn't make him a genius, it was just common sense.
Yeah, like common sense is now to move Kalvin into central defence and use him.
We signed him for 40, right now we are unable to sell him even for 10m I guess.
He showed his potential as a CB and therefore can give Pep more flexibility in terms of tactics.
------------------------Ederson / Ortega-------------------------------
----Walker/Rico--------Ruben/Kalvin-----------Guardiol/Ake------
---------------John/Akanji-----------Rodri/Kova-----------------------
Bernie/Savio---KDB/Macatee-----Foden/Matheus--Grealish/Doku
----------------------------Haaland/Bobb/Alvarez?----------------------
Se let's imagine we don't sign any new players other than Savio and don't sell anyone as well..
We have two players Ederson and Alvarez, who we aren't sure about, but other ones will stay.
It means that Rodri replacement is still an issue. Cause against the bigger teams, replacing Rodri with Kovacic, won't be as productive, as we wished to. And mainly it will cost us in ball possession and build-ups, as we won't be as solid in that areas, as we are with Rodri.
Kalvin as a CB, with his long-ball-deliveries, can help us to balance those areas, when Rodri isn't on the pitch. Yep as a defender he may not be as good as Ruben is or other ones, but when Rodri isn't on the pitch, defence isn't the most important one to think about.
So like....
------------------------Ederson----------------------------
-------Walker---------Kalvin-----------Guardiol---------
----------------John------------Kova-----------------------
Bernie--------KDB-------------Foden-----------Grealish
------------------------Haaland-----------------------------
This 11 for me is better with Kalvin, than with Ruben or other ones, when it comes to covering for Rodri.
