Borussia Dortmund star Marcel Sabitzer has sung the praises of his old coach at Manchester United.

Sabitzer was on loan at the Red Devils during the second half of last season under Erik ten Hag.

He has now heaped praise on the Dutch head coach, who is under pressure and in danger of losing his job this term.

“You can wake him up at 3am, he'd tell you his whole match plan by heart," Sabitzer told The Athletic.

"He's very knowledgeable about football and tactics — a very hard worker, a perfectionist. And he's very straight with you. When I had a bad game, he showed me some situations and told me how to do it better next time. I liked that.

"You knew where you stood with him. He never threw you under the bus. Instead, he told players to go out and do better in the next game. I learned a lot about football working under him. He's a very good coach."
