"I have to take a few difficult decisions about who should be in the 18 and who should be in the XI," Hasenhuttl said at his pre-match press conference.

"I think a lot of players deserve to be in this squad, and there are still one or two positions where I am not completely sure. But in the end, everybody knows their chance will come.

"Scoring in pre-season was not the biggest problem for us, but it's only pre-season. The first game in the Premier League is something completely different.

"They know what they have to do to get a good balance together; opposite runs, how to play together, working against the ball. We've worked a lot in this part of the game.

"Che Adams had the big advantage that he was here from the beginning of pre-season and that helps him a lot. For Moussa, it is a little bit more difficult and it will take time to bring him into the squad.

"He has shown in the first two weeks he has a lot of skills that can help us. For the tactical skills, I think he needs more automatism, but he is open minded and very positive. He's a good character and I like him.

"Danny Ings is very fit and he invested a lot in the break, not only the pre-season. He scored, worked hard and it's a big battle in the front for these three positions.

"We have Michael Obafemi who showed up in the pre-season and Shane Long, who doesn't want to step back, and Stuart and Sofiane, who is back with a lot of quality. These positions are the ones with the biggest battle so far."
