Lol @ the world record defender needing other components to work.
That's almost as farcical as the world record midfielder needing other midfielders to "unlock" him.
He needs other components because we like to press and play higher. If we still had Mourinho he'd be protected as we'd be sitting on the edge of the 6 yard box 90% of the game and people would be all over his dikk.
He can still work in a high line but he needs people with other strengths to protect his weaknesses. Just like his aerial strength for the most part covers up the weakness of others in that respect.
Vidic had similar weaknesses which Rio helped to hide. Just as Vidic helped Rio who wasn't overly dominant in the air.
Like this is basic stuff i'm not sure why i just bothered to explain it.
