Norway coach Stale Solbakken feels Manchester City striker Erling Haaland's busy schedule caught up with him.
Haaland has now recovered from a foot stress fracture.
“It's art," Solbakken said. "Erling has an explosive style of play.
“The package he has been given and then physically acquired will explode and perform maximum actions on Sunday-Wednesday-Saturday every week in a normal season. He is the type of player who lives on power and explosion. Those who are exposed to it must take even more care of their bodies than others. But Erling has the body of a god - and it means taking care of that type of body.
“It is also something I have to think about as a coach. He has to be part of what we do when we don't have the ball, but it's not possible to ask him to do that constantly. The body can't stand it. How many times during a match can he explode?"
