Mats Hummels was so exhausted and euphoric after winning the World Cup that he felt “like I’m on another planet.”
The German defender spoke to FIFA following a 1-0 victory in extra time over Argentina. 
“I feel like I’m on another planet, as I am too physically exhausted to celebrate and too euphoric to focus.
“You can only become world champions if you work as a team. We wanted to make that point clear to everyone at all times and we achieved it.”
Mario Gotze came off the bench to score the winner at the 113th minute.
“We did need a little bit of luck in the Final, as we were practically already preparing for a penalty shoot-out.”
