Borussia Dortmund star Thomas Delaney believes that striker Erling Braud Haaland always wants to improve.

The Norwegian has been with the club for nearly half a season after arriving in January.

He has hit the ground running, impressing fans around Germany with his goalscoring prowess.

But Delaney is most impressed by how hard Haaland works and how much he is willing to learn.

"I see a young man [Haaland] that does everything to improve," the BVB midfielder told ESPN.

"This guy is annoying sometimes because everything has to be on point with more training and eating better.

"I think he's benefited from having people around him, especially his dad, that knows how things work in football. With Erling, I don't even have to mention the stats.

"With Gio as well, just coming in, an American kid last year, travelled a lot back and forth and still has his breakthrough to come but he's a player you can expect more from him because in training he's on a level."
