Bayern Munich are considering legal action after their left back Alphonso Davies returned from international duty for Canada with a severe knee injury, club officials said on Friday.
"We demand that Canada Soccer provide a complete explanation of what happened and expressly reserve the right to take legal action," Bayern CEO Jan-Christian Dreesen told the Bild paper.
Sporting director Christoph Freund said in a news conference ahead of Saturday's Bundesliga match against St Pauli that "we want to clear it up completely."
Davies ruptured the cruciate ligament in his knee last weekend in Canada's Nations League match for third place against the United States.
