Borussia Dortmund legend Karl-Heinz Riedle has slammed Ousmane Dembele for the way he engineered a move to Barcelona during the transfer window.
Dembele moved to Camp Nou in August for an initial €105million, with add-ons potentially taking the deal up to €147m.
His switch came after the 20-year-old went on strike in a bid to force Dortmund's hand, with Dembele refusing to train with Peter Bosz's side.
Dembele – who is currently sidelined with a hamstring injury – has no regrets about the action he took, but Riedle says the forward should have been punished for his actions.
"[He made a] massive impact, we knew it was difficult to keep him, [but] he wanted to play for Barcelona," Riedle – who scored twice when Dortmund won the Champions League final in 1997 – told Omnisport.
"I didn't like how it went, how he pressured it's a joke.
"You should be banned for doing like this."
He added: "You never know with Aubameyang, maybe he'll stay at Dortmund forever."
