Norway manager Stale Solbakken claimed Erling Haaland was "completely empty" before being withdrawn against Scotland on Saturday.
The Manchester City striker put his country in front against the Scots as they looked to pick up a valuable three points. The score was still 1-0 when he left the field, but two late goals for Scotland turned the game on its head.
Haaland's goal from the penalty spot was his first in six games for club and country as the Premier League's top scorer saw his scoring dry up. Now, Solbakken's comments may come as a worry ahead of Tuesday's must-win game against Cyprus.
