I saw almost every match of KDB in the past 3 years and what happened was normal.It was his average level....nothing outstanding.
His goal was normal. A typical KDB goal. Very clean finishing.
He can do it as easy with his left foot to . In terms of using left and right foot he is together with Sneijder ,Messi and Ronaldo in their own league.
Yesterday also showed that he should always play central behind the striker. No switching stuff. He can deliver so much more central. A real game breaker witch are rare in world football. So you should profitate from that as much as possible. Thats why he has to play central also when Silva is back.
