Borussia Dortmund chief Hans-Joachim Watzke says there's no grudge against super agent Mino Raiola.

Raiola managed to ferry Henrikh Mkhitaryan away from BVB to Manchester United over the summer.

Reflecting on the move, Watzke told Kicker: "Raiola is intelligent, and he is brutal.

"He has a certain business model, but we knew that when we sat down with him for Mkhitaryan. He knows what you have.

"Raiola has behaved properly throughout the Mkhitaryan process."

Asked if Raiola drove the deal, Watzke added: "I will not comment. It was 100 per cent the player's decision."
