Blah blah blah blah
Yes he has dipped in form but put anyone in a dysfunctional backline like ours has been over the past few years due to pep trying to fit in cesc with the 3-4-3, and titos crapness and they will struggle, replace him with any top defender and the would look bad, yes he has lost form but in a lot of these games he has not been as bad as people make out, they just expect him to do everything, since he is the only one in the back line they can look to.
How has he looked for Spain yes you can see a bit of a dip but he has been very good none the less, as I always said and what I have not in a long time, but needs to be said this season and not just related to him but a few players in the team (except cesc)
The individual star comes out to shine when the collective balance of the team is right.
Individually every signle member of the barca Xi is world class, have they looked it over the past two seasons, and especially this one?. No because their is no balance in the team
Get a solid defender beside him, and a proper fullback or the right or left and see what happens.
