Jurgen Klopp, manager of Liverpool, expressed surprise at Sadio Mane’s unsuccessful transfer to Bayern Munich.
Mane departed Anfield last summer after seven years to join the Bundesliga’s top club.
Senegal’s winger, who had recently won two championships with the Reds by finishing as runners-up in the Premier League and Champions League, was acquired by Bayern for about £34 million.
However, Mane’s one season was a nightmare as Bayern changed managers and he had a public altercation with teammate Leroy Sane.
Mane has now signed a £650,000 per week contract with Al Nassr.
“I don’t know what went wrong at Bayern.
“When he left us, he left us on a high in really good shape, a world-class player.
“New environment, new expectations maybe. I didn’t speak to Sadio about it,” Klopp said.
