Manchester City signing Erling Haaland admits last season's injury problems were frustrating.

Haaland missed 35 per cent of injuries with Borussia Dortmund last term.

He said, "It has not been optimal. I can say that right away. There have been little things here and there.

"From treatments I have received, things I have trained on and things I have done, I've learned a lot about my body. I've still played a couple of games this year. I have scored a couple of goals.

"It has not been a complete disaster. But it has not been optimal. Normally I should be at 40-50 games a year. I have not done that this year. It is important to work to get to that level."
