Borussia Dortmund chief executive officer Hans-Joachim Watzke has hinted that Pierre-Emerick Aubameyang's decision to leave the club and join Arsenal was motivated by money.
Watzke spoke to Suddeutsche Zeitung (h/t the Mirror's Alex Richards) about the striker who left the Bundesliga side in January 2018:
"Of course it is hard to keep a player in the face of such sums. Some go to clubs because of this money, where they have not played Champions League for years. Aubameyang, who plays great at Arsenal, will probably be warm-hearted when he looks at his bank account, but on Wednesdays will be saddened when he has to watch the Champions League on television.
