Davinson,Lemos,Malang sarr seemed to be up Robert's alley when it comes to CBs. Yerry was very likely scouted and well liked by our South American scouts, Miguel Rico mentioned back in December was it? that Robert at the time has yet to watch Yerry play.
I think Yerry to the club was one of those "To good" to pass up kinda deals regardless if he fits the Barca CB style. He's talented without a doubt and many consider him the best CB in Brazil last season, it's not like it's some random player we are following.
I feel like we are in a good spot when it comes to CBs. Which is good considering for a time all we had was Pique-Mascherano, a Puyol who was aging and injury prone and a very raw Bartra, who everyone seemed to debate whether or not he was top level talent and lets not forget playing Song as a CB and at times even Busi.
