Borussia Dortmund chief Hans-Joachim Watzke insists they did good business over the sale of Pierre-Emerick Aubameyang.

Watzke feels their deal with Arsenal will be the striker's last big move of his career.

The Gunners splashed out €63m for the Gabon international last week and despite losing the experienced forward, Watzke says they can be happy with the money made.

"We've never had a bigger offer for him," said Watzke.

"He will not get sold any more. At most, if he's up to something, at some point again he'll go to China."
