Witsel played excellently for Belgium at the World Cup, proving that he is a top quality player.
The 29-year-old sounds pleased about this transfer as he told reporters:
“After the World Cup, my goal was to move from China back to Europe. I’m totally happy and proud to play for BVB soon,” said Witsel.
“After our first conversation, I did not have to think twice, because for me Borussia Dortmund is one of the best clubs on the continent. Honestly, I can not wait to run aground in front of 81,000 people.”
